電池・電解装置・歯・半導体をはじめとする複雑なヘテロ界面状態は、熱、水分、化学反応、電気化学反応・外的な力学負荷などにより動的に大きく変化する。動的に変化する界面状態を物理・化学・電気化学・材料科学・熱力学をはじめ複眼的視点から明らかにすることを目標として研究を推進している。
本研究では、時間依存型変形の典型であるクリープなども含めた拡散現象と数年オーダーの中・長期的な力学変化を迅速かつ正確に推定することに挑戦している。動的に変化する物質にアクティブなパルス波やテラヘルツ波、赤外線などの弾性波・電磁波を与えてその特徴量を数値化・関数化することで高速なヘテロ界面変化挙動を捉えることに挑戦している。
加えて、過酷な環境での長期寿命を含めた変化挙動予測を結晶構造・電気化学・変形応力・流体連成数値シミュレーションで行うために物性評価や数値解析モデル化に加えて実験での検証を行うことでを様々な視点からの検討を試みている。
今年度は、２次元データからの３次元構造予測や数時間の実験から数年先の微細構造まで予測できる可能性を見出すことができた。深層学習との併用で数時間の短期だけでなく中・長期ヘテロ界面構造変化も深層学習を取り入れた数値シミュレーションで予測できるようになってきた。実験データやシミュレーション結果との比較を行うことで極めて確度の高い予測結果を出せることが示された。今年度は新たな学術領域の芽を見出せるようにまとめていく予定である。 -

This study developed the novel self-pulverisation oxides and elucidated the self-pulverisation mechanism. The results based on XRD, SEM, and EDX demonstrated that a small amount of excessive LaCoO3 mixed in oxides hydroxylates with a significant volume expansion, eventually causing the pulverisation of oxides. The local stress distribution and critical crack length around excessive LaCoO3 particles are estimated. Various conventional ceramics were successfully pulverised by controlling the excessive amount of LaCoO3 and the atmosphere.

The present research studied both the mechanics and ionic aspects of oxygen-ion conducting perovskite oxides for ionic devices such as fuel cells and separation membranes. The experimental methods and simulation techniques for the evaluations were developed, based on which the mechanical behaviour, especially ferroelastic behaviour, the ionic diffusion, and their correlation were partially elucidated. In addition, the mechanical behaviours and ionic diffusion in the lithium-ion conducting perovskites for all-solid-state batteries were investigated.

This research is basic/applied research aiming to dramatically improve performance, durability and reliability by creating fuel cells and secondary batteries from ceramics and metals. The obstacle to the commercialization of solid state batteries is due to the fact that they are mainly composed of ceramic members with extremely low mechanical reliability. Therefore, in this research, we have succeeded in developing a battery that combines performance, durability, and reliability by combining some of the battery components with a metal having a nano-porous structure. In addition, we succeeded in developing the world's first non-destructive evaluation method that can quickly evaluate the stability of the interface structure.

Surface segregation in ionic solids is one of the main causes of degradation of ionic devices such as solid oxide fuel cell. The present study investigated the surface segregation phenomenon in La-Sr-Co-Fe-O (LSCF) subjected to mechanical stress. The results suggested that mechanical stress, especially compressive stress, which can aid high temperature creep deformation without grain boundary sliding, could suppress surface segregation in LSCF.

The present study investigated ferroelasticity and ionic conductivity of mixed ionic-electronic conductive perovskite oxides. The present experimental and analytical results elucidated the ferroelastic mechanical behaviours of various lanthanum-based perovskite oxides such as LaCoO3-d in a wide range of temperature. Additionally, new techniques for evaluating the oxygen deficiency and ionic conductivity of these materials under uniaxial compression at elevated temperature was established. The result suggests the effect of compressive stress on the deficiency and conductivity.

An analytical method to predict strain fields in multi-layer quantum dots solar cells during its fabrication processes. The strain field due to material combination, interface direction, external strain are given using the developed methods. The change in energy bands due to strain is described through combination of strain components. An interface elasticity between the dot material and matrix material is considered to predict the strain field near the dot-matrix interface and its influence is evaluated. A continum mechanical theory to include the interfacial elasticity is applied to the quantum dot problem.

An improvement in the estimation of the location of embedded InGaAs/GaAs quantum dots (QDs) by using a domed-apex probe to perform the low- temperature (10 K) photoluminescence (PL) measurement during a nanoprobe scan was established. Fine PL peak from individual QDs was enhanced with the nanoprobe-induced strain. Tracing the PL emissions of single QD with the movement of the probe position in the scan, the locations of some of observed QDs were obtained directly from the scan results, at where the PL peak energies of those QDs achieved maximum values.

Effect of bi-dispersing spherical silica particles on mechanical properties of epoxy composites were investigated experimentally and also analyzed using model of particle dispersion theoretically. The materials of specimens used in this study were bisphenol A-type epoxy composites reinforced by different spherical silica particles; nano-silica particle with 240 nm in diameter and micro-silica particle with 1. 56 mm in diameter. The specimens had different particle size compositions. We measured mechanical properties, namely thermo-viscoelasticity and fracture toughness, of the composites. The viscoelastic properties of the composites in glassy state were independent of particle size and governed by total volume fraction of the particles. The properties in rubbery state were found to have dependency on particle size due to increasing particle mobility. Distance between randomly-distributed particles for each composite was analyzed numerically by Bansal and Ardell's statistics method. The nearest surface distance of randomly-distributed particles is dependent on the volume fraction of the particles and proportional to its diameter. Then, based on similar particle distribution for each composite having the same volume fraction of the particles, we constructed theoretical model and considered mixture law of fracture toughness for single-particle dispersed composite. We found that the fracture toughness of the composites was approximately linear with respect to the reciprocal of the product of (i) the square root of the mean distance between the particle surfaces, and (ii) the normalized mean stress in the matrix given by the equivalent inclusion method. The theoretical result agreed well with the experimental results. However the mixture law of fracture toughness included the unknown parameter which was predicted to be related to interaction between particle and cxosslink structure of polymer matrix. Therefore, we clarified that the thermo-viscoelastic properties of particles bi-dispersed composites in glassy state are determined only by total volume fraction of the particles and the fracture toughness are done by distribution of particle size and the volume fraction. Based on this conclusion, we obtained that thermo-viscoelastic and fracture properties of the composite can be tailored independently.

エポキシ樹脂の不均一硬化による巨視的機能の発現

本研究は,エポキシ樹脂の不均一硬化が発現する巨視的機能を明らかにすることを目的としている.平成16年度は,比熱容量と誘電率に着目し,不均一硬化が与える影響を明らかにすることを目的として,単一モノマー試料(均一)と,二種類のモノマーを配合した混合モノマー試料(不均一)を作製し,モノマーの分子量およびその分布の影響について調べた.
示差走査熱量計により熱量測定を行い,各試料の比熱容量の温度特性を調べた.単一モノマー試料については,硬化前のモノマーの分子量が小さいほど,高いガラス転移温度を示した.混合モノマー試料については,試料全体の平均分子量には依存せず,配合した各モノマーの特性が独立に現れた.
変成器ブリッジ法により静電容量・コンダクタンス測定を行い,各試料の複素誘電率の温度・周波数特性を調べた.単一モノマー試料については,硬化前のモノマーの分子量が小さいほど,低周波数あるいは高温においてガラス転移した.混合モノマー試料については,比熱容量と同様,試料全体の平均分子量には依存せず,配合した各モノマーの特性が独立に現れた.さらに,複素誘電率の周波数依存性にHavriliak-Negamiモデルを適したところ,単一モノマー試料は単一緩和モデル,混合モノマー試料は二重緩和モデルで表されることが明らかになった.混合モノマー試料における二つの緩和時間は,配合した単一モノマーの緩和時間にほぼ等しく,各分布は広くなった.一方,混合モノマー試料の緩和強度は,平均分子量に影響を受けた.このような二重緩和は,モノマーの分子量・その分布だけでなく,硬化後の網目鎖の分布に大きく起因していると考えられる.
以上より,エポキシ樹脂の比熱容量および複素誘電率は,モノマーの平均分子量だけでなく,モノマーの分子量およびその分布,さらに網目鎖分布による不均一硬化に大きな影響を受けることがわかった. -
