Abstract With the development of communications technology, copper‐clad laminate (CCL) for integrated circuits (IC) pointed to direction high‐frequency and high‐speed development, that is, a lower dielectric constant loss requirements. Bismaleimide (BMI) resins feature stable properties excellent thermal stability over wide temperature range, widely used in manufacture CCL substrates. However, comprehensive performance BMI resin itself, including properties, still cannot fully meet needs ever‐changing industry, so molecular design modification enhance is currently one key research directions circuit CCL. This paper reviews their applications, focusing on main methods formulation optimization, allyl, diamine, internal chain‐extended, chemical/physical blending modification. Finally, low its application are summarized prospected. Future include synthesis multi‐component copolymers further realize balance between performance, as well exploring possibility novel composite modifications provide more competitive high‐performance materials IC field. Highlights The bismaleimide applications reviewed. monomers' chemical reaction summarized. modified

Highly improved mechanical and thermal properties of bismaleimide via a novel thermoplastic isoindolinone polyether sulfone

Polymer Engineering and Science, Год журнала: 2025, Номер unknown

Опубликована: Апрель 13, 2025

Abstract To improve the mechanical and thermal properties of thermosetting bismaleimide resins, a novel thermoplastic isoindolinone‐based polyether sulfone (PES‐In) resin was synthesized as toughening agent for N , ′‐(4,4′‐methylenediphenyl)bismaleimide/2,2′‐diallylbisphenol A (BDM/DABPA) system. The incorporation this not only enhanced material's overall toughness but also significantly improved its performance. effects PES‐In's viscosity dosage on efficiency were systematically studied, leading to identification optimal conditions. Specifically, 7.5 phr PES‐In with 0.4 dL/g resulted in remarkable increase impact strength PES‐In/BDM/DABPA system 37.20 kJ/m 2 representing 497% improvement over base BDM (6.23 ). Thermal properties, assessed by dynamic thermomechanical analysis thermogravimetric analysis, showed significant enhancements, T d5% g reaching 425 267°C, respectively, storage modulus rising from 2.0 2.5 GPa. Scanning electron microscope revealed typical “sea‐island” structure multiple crack deflections fracture surface. introduction thus broadens application potential higher‐temperature‐resistant structural materials. Highlights Novel synthesized. Toughness networks improved. performance PES‐In/ /DABPA Relative mechanism clearly elucidated.
