The dielectric constants (Dk) and dissipation factors (Df) of 11 types of polyimides (PIs) were systematically measured between 25 and 330 GHz using Fabry–Pérot resonators. Herein, the relationships between their frequency dependence and chemical structure are discussed. As the frequency increased, all the PIs exhibited a continuous decrease in Dk and a consistent increase in Df. Notably, no distinct peaks were observed over the entire frequency range. The decrease in Dk with frequency gradually approached the square of the refractive index (n2) in the near-infrared region. Additionally, based on the correlation between the dielectric dispersion and dielectric polarization (Pt), Dk showed a stronger correlation with the electronic polarization (Pe) at higher frequencies than with the dipolar orientational polarization (Pd). Moreover, in fluorine-containing PIs, Dk declined faster with increasing frequency as the fluorine content (F%) increased. Meanwhile, the increase in Df showed a negative correlation with the weight fraction of polar groups (polar%), and the PIs containing –CF3 groups in the diamine moieties exhibited a similar rapid increase in Df with frequency, suggesting characteristic absorptions in the terahertz (THz) domain. These data will be beneficial for developing high-performance polymer-based insulating materials for 5th/6th generation wireless communication technologies.

Overcoming the entropy of polymer chains by making a plane with terminal groups: a thermoplastic PDMS with a long-range 1D structural order Reviewed International journal

Language：English Publishing type：Research paper (scientific journal)

Due to its unique physical and chemical properties, polydimethylsiloxane (PDMS) is widely used in many applications, in which covalent cross-linking is commonly used to cure the fluidic polymer. The formation of a non-covalent network achieved through the incorporation of terminal groups that exhibit strong intermolecular interactions has also been reported to improve the mechanical properties of PDMS. Through the design of a terminal group capable of two-dimensional (2D) assembly, rather than the generally used multiple hydrogen bonding motifs, we have recently demonstrated an approach for inducing long-range structural ordering of PDMS, resulting in a dramatic change in the polymer from a fluid to a viscous solid. Here we present an even more surprising terminal-group effect: simply replacing a hydrogen with a methoxy group leads to extraordinary enhancement of the mechanical properties, giving rise to a thermoplastic PDMS material without covalent cross-linking. This finding would update the general notion that less polar and smaller terminal groups barely affect polymer properties. Based on a detailed study of the thermal, structural, morphological and rheological properties of the terminal-functionalized PDMS, we revealed that 2D assembly of the terminal groups results in networks of PDMS chains, which are arranged as domains with long-range one-dimensional (1D) periodic order, thereby increasing the storage modulus of the PDMS to exceed its loss modulus. Upon heating, the 1D periodic order is lost at around 120 °C, while the 2D assembly is maintained up to ∼160 °C. The 2D and 1D structures are recovered in sequence upon cooling. Due to the thermally reversible, stepwise structural disruption/formation as well as the lack of covalent cross-linking, the terminal-functionalized PDMS shows thermoplastic behavior and self-healing properties. The terminal group presented herein, which can form a 'plane', might also drive other polymers to assemble into a periodically ordered network structure, thereby allowing for significant modulation of their mechanical properties.

It is generally considered that the chemical structures of the junction points of brunched polymers do not largely impact on their properties, because the contribution of a junction point is small with respect to the whole polymer length and gravity. However, we recently found that three-arm star-shaped polymers with a junction point consisting of a tripodal triptycene exhibit significantly different properties from those of three-arm star-shaped polymers with other junction points. In this study, we investigated the remarkable assembling behavior and rheological properties of the triptycene-containing star-shaped polymers.
