The correlations between the molecular structures of four Tröger's base (TB)-based polyimides (PIs) and two non-TB containing analogues physical properties including thermal conductivity (λ) dielectric both at low high frequencies were investigated in detail. TB-based PI films exhibited constants (Dk = 2.25–2.80) 10 GHz. They possessed much lower λ values (0.035–0.145 W/mK) compared to commercial Kapton (0.240 W/mK). influences incorporating TB units into chain backbones on aggregation PIs identified. Incorporating effectively reduced degree orientation increased fractional free volume, leading Dk for resulting films. Also, introducing enhanced weights, toughness, glass-transition temperature (Tg) PIs. Therefore, can be promising heat-insulating low-k materials.

Dielectric properties of polyimide (PI) are constrained by its inherent molecular structure and inter-chain packing capacities. The compromised dielectric PI, however, could be rescued introducing trifluoromethyl forming a host-guest inclusion complex with the introduction crown ethers (CEs). Herein, we report PI/crown ether composite films as communication substrate that applied under high frequency circumstances. In this work, three kinds bisphenol A-containing diamine (2,2'-bis[4-(4-aminophenoxy)phenyl]propane, 2,2-bis[4-(2-methyl-4-aminophenoxy)phenyl]propane, 2,2-bis[4-(2-trifluoro methyl-4-aminophenoxy)phenyl]propane) synthesized polymerized 4,4'-(hexafluoroisopropylidene)diphthalic anhydride to prepare low-dielectric PI means thermal imidization. Crown introduced into different mass fractions obtain series films. Following combination chain loss modified can effectively reduced. these materials (especially properties) thoroughly explored addition. results show addition process offer increased free volume matrix, thus allowing them generate special necklace-like supramolecular structure, which makes disperse more uniformly in resulting improved properties. Importantly, constant at frequencies remarkably reduced 2.33 0.00337, respectively. Therefore, expected find extensive use 5G future.
