“…A number of aromatic polymers, such as polyimides (PIs), poly(aryl ether)s (PAEs) and poly(aryl ether ketone)s (PAEEKs), have been proposed as low k materials due to their excellent thermal stability [5][6][7][8]. These aromatic polymers with k of 3.1-3.9 at 1 MHz are often insoluble and infusible due to their rigid chain characteristics, which lead to processing difficulties and hinder their application in industries.…”

A new fluorene-based bisphenol monomer containing pendant tert-butyl groups, 9,9-bis(3-tert-butyl-4-hydroxy)phenyl-fluorene (BTHF), was readily synthesized in high yield by a one-step reaction from inexpensive starting materials. The resulting poly(aryl ether) (FPAE 3) was successfully prepared by a mild nucleophilic aromatic substitution reaction using this fluorene-based bisphenol and decafluorobiphenyl. The obtained poly(aryl ether) exhibited good solubility in some low-boiling-point solvents and could be cast into flexible and strong film. It displayed high thermal stability with glass transition temperature at 264°C and 5 % weight loss temperatures at 487°C in air atmospheres. Moreover, it revealed low dielectric constants with the value of 2.64 at 1 MHz measured for its capacitance.

“…PEEKs with greater hydrophobicity and better dielectric properties for microelectronic devices were prepared by nucleophilic substitution polycondensation of fluorophenyl and difluorophenyl hydroquinones with difluorobenzophenone [Figure (c)] . The contact angle of water for solution‐cast films increases from 83.9° for PEEK to 90.3° and 98.4° for mono and difluorophenyl‐substituted PEEKs, respectively.…”

Interest in carbon fiber reinforced composites based on polyaryl ether ketones (PAEKs) continues to grow, and is driven by their increasing use as metal replacement materials in high temperature, high-performance applications. Though these materials have seen widespread use in oil, gas, aerospace, medical and transportation industries, applications are currently limited by the thermal and mechanical properties of available PAEK polymer chemistries and their carbon fiber composites as well as interfacial bonding with carbon fiber surfaces. This article reviews the state of the art of PAEK polymer chemistries, mechanical properties of their carbon fiber reinforced composites, and interfacial engineering techniques used to improve the fiber-matrix interfacial bond strength. We also propose a roadmap to develop the next generation of high-performance long fiber thermoplastic composites based on PAEKs.

“…In recent years, polymeric materials have drawn more attention due to their good dielectric, thermal, and mechanical properties, as well as solution processability . A large number of polymers have been investigated for this application, such as epoxy‐based materials, polyimides, polybenzoxazoles, polynorbornene, poly(arylene ether sulfone)s, and poly(arylene ether ketone)s (PAEKs) . Poly(arylene ether ketone)s have been used as high performance engineering plastics, due to their high mechanical properties, good electrical characteristics, excellent thermal stability, and chemical resistance.…”

A low dielectric constant poly(arylene ether ketone) containing naphthalene and trifluoromethyl groups (FPNAEK) were prepared and characterized. The FPNAEK showed excellent thermal stability (Td5 = 443 C ) and low water absorption. The dielectric constant decreased significantly after introducing trifluoromethyl group, in comparision with poly(arylene ether ketone) containing naphthalene (PNAEK). The dielectric constant of FPNAEK is about 2.5 between 1 kHz and 1 MHz at room temperature, which is much lower than that of commercial poly(ether ether ketone) (3.3) and PNAEK (2.78).
