“…Polyarylene ether nitriles (PENs) are a kind of super engineering materials with high-temperature resistance, great electrical insulation, adjustable dielectric constant, and excellent mechanicals. These advantages enable the polymer to be applied in many fields, such as polymerinsulating substrates used in flexible printed circuit boards, 31 interlayer dielectric materials, [32][33][34][35][36] Li-battery separators, 37,38 and corrosion fields. 39 However, the low intrinsic TC and high thermal expansion coefficient of PENs seriously affect their applications in cutting-edge electronic fields.…”

Thermal conductive polymer‐based composites synchronously with stable dielectric and excellent mechanical properties are urgently needed for high‐temperature‐resistant electronic devices. Here, a significant improvement in the thermal conductivity (TC), thermal stability, dielectric, and mechanical performance was simultaneously achieved in the polyarylene ether nitrile (PEN)/divinyl siloxane‐bisbenzocyclobutene (BCB) matrix through the incorporation of boron nitride nanosheets (BNNS) combined together with the post‐solid phase chemical reaction technique. The significant increase in the effective filler‐filler and filler‐crystal contacts in the composites was the main reason for the improvement in TC and dielectric constant. Besides, glass transition temperature (Tg) and mechanicals were enhanced in the presence of cross‐linked networks. By synchronously adding 15 vol% BNNS, the TC of composites after treatment reached up to 5.582 W/m.K, enhanced by 4.4 times higher than untreated. The dielectric constant was down to 2.93 at 1 MHz and the loss remained at a relatively low level. Meanwhile, the composite showed significantly enhanced thermal stability, mechanicals, and hydrophobicity (Tg = 336°C, T5% = 529°C, tensile strength and modulus was 94.5 MPa and 5.3 GPa, respectively, the contact angle was 101.76°). Thus, it promotes an effective strategy for fabricating a high‐performance‐polymer composite, which has the potential used in electronic materials.Highlights Crystallization‐crosslinking strategy optimizes overall performance. Crystals fill gaps between BNNS layers and connect thermal conductive pathway. Crosslinked networks limit molecular chain motion to reduce phonon scattering. The highest TC of the PEN/BCB/BNNS composite is up to 7.451 W/m.K. Thermal property shows significant improvement after crosslinking especially Tg.

Semi‐crystalline poly (arylene ether nitrile) (PEN) with outstanding thermal stability and mechanical properties are expected to be used in structural materials. Increasing the crystallinity of PEN helps improve the processability of the materials as well as the thermal and mechanical properties of the products. In present work, the comprehensive properties of PEN composites are improved by the introduction of aramid staple fiber combined with hot stretching method. The effects of aramid fiber content and hot stretch multiplicity on the properties of the composite were investigated. The result shows that when the mass fraction of aramid fiber (AF) powder is 0.3% (PEN/AF3), the composites have the best overall performance, including thermal and mechanical properties. In addition, when the tensile ratio was 300% (PEN/AF3‐300), the properties of the samples are greatly improved, with the crystallinity increasing to 36.1%, the thermal decomposition temperature of 5% (Td5%) increasing by 10°C, and the tensile strength increasing to 195.40 MPa, which is 87.34% higher than that of the non‐thermal tensile composites. Therefore, this work provides a technical route for the preparation of high performance semi‐crystalline PEN composites, which is beneficial for the development of PEN applications.
