Abstract Polyimides (PIs) are widely used in circuit components, electrical insulators, and power systems modern electronic devices large appliances. Electrical/mechanical damage of materials important factors that threaten reliability service lifetime. Dynamic (self‐healable, recyclable degradable) PIs, a promising class successfully improve electrical/mechanical properties after damage, anticipated to solve this issue. The viewpoints perspectives on the status future trends dynamic PI based few existing documents shared. main forms dielectric application process first introduced, initial strategies schemes these problems proposed. Fundamentally, bottleneck issues faced by development PIs indicated, relationship between various universality method is evaluated. potential mechanism deal with highlighted several feasible prospective address discussed. This study concluded presenting short outlook improvements systems, challenges, solutions insulation. summary theory practice should encourage policy favoring energy conservation environmental protection promoting sustainability.

Polymers are essential components of modern-day materials and widely used in various fields. The dielectric constant, a key physical parameter, plays fundamental role the light-, electricity-, magnetism-related applications polymers, such as electrical insulation, battery photovoltaic fabrication, sensing contact, signal transmission communication. Over past few decades, numerous efforts have been devoted to engineering intrinsic constant particularly by tailoring induced orientational polarization modes ferroelectric domain engineering. Investigations into these methods guided rational design on-demand preparation polymers with desired constants. This review article exhaustively summarizes from molecular mesoscopic scales, emphasis on application-driven polymer synthesis rooted chemistry principles. Additionally, it explores that can benefit regulation outlines future prospects this field.

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.
