Epoxy acrylate (EA) resins have excellent light-curing properties and play a crucial role in UV-curable resins, but poor mechanical properties, lower thermal stability, and stronger hydrophilicity hinder their applications in high technic areas such as circuit board printing and electronic packaging. In this study, to enhance UV-curing EA resins, a photosensitive polyimide (PSPI) with a highly rigid and twisted skeleton was developed as a macromolecular cross-linker. This PSPI is featured with a unique diamine monomer that possesses a spirocyclic fluorene-xanthene core double-grafted with methacryloylamino groups. Commercial EA resins (EB600) were blended with varying levels of PSPI to modify the density and structure of the cross-linked network of the EB resins. The methylacrylamide groups branching on xanthene rings in the PSPI participate in radical UV-curing by crossing over with the main-chain helixes, resulting in threedimensional cross-cured networks and unique structural rigidity of the resins. EB resins with different PSPI contents demonstrate apparently improved overall properties, compared with the nonmodified EB600. Among these cured resins, the overall performance of EB 10 PSPI 1 (weight ratio of EB/PSPI 10/1) was superior. The initial thermal decomposition temperature (T d5% ) of EB 10 PSPI 1 resin is 353 °C, 78 °C higher than that of EB 1 PSPI 0 (without PSPI), and the residual carbon rate is increased by 12.36% at 600 °C. The T g of EB 10 PSPI 1 resin was 122 °C, while that of EB 1 PSPI 0 resin is only 87 °C. The tensile strength and modulus of elasticity of EB 10 PSPI 1 resin increased by 162 and 246%, respectively, and the hardness increased by 291 MPa compared with EB 1 PSPI 0 resin. In addition, the surface of EB 10 PSPI 1 resin exhibited good hydrophobicity with significantly lower water absorption and swelling rate than that of EB 1 PSPI 0 . Also, EB 10 PSPI 1 exhibits good adhesion capability. Finally, the curing performance of the EB 10 PSPI 1 resin is better, almost doubling the curing speed at weak UV-light irradiation intensities, demonstrating the excellent sensitivity of the PSPI in radical polymerization reactions and the enhancement of the UVcuring network of the EB resin. This study opens a way to comprehensively enhance the thermodynamic and mechanical properties of EB 1 PSPI 0 resins, which is promising in circuit board printing and electronic packaging.

Purpose This paper aims to investigate the effects on coatings performance in the epoxy silicone resin system owing to the existence of the different chain length of open-chain epoxy monomer. In this paper, [4-Methylphenyl-(4–(2-methylpropyl) phenyl)]iodonium as photoinitiator was added into epoxy silicone resin by ultraviolet (UV)-cured polymerization to investigate the effects on coatings performance owing to the existence of the different chain length of open-chain epoxy monomer. Design/methodology/approach A simple hydrosilylation reaction was used to synthesize epoxy-based silicone prepolymers by using hydrogen-terminated polydimethylsiloxane, 1,2-epoxy-5-hexene, 1,2-epoxy-7-octene and 1,2-epoxy-9-decene as precursors. Findings The results revealed that the glass transition temperatures (Tg) and hydrophobicity increased with the chain length of open-chain epoxy monomer in the UV curable epoxy-based silicone coatings, and these films had excellent heat resistance, hydrophobicity, antigraffiti and ink removal properties. Research limitations/implications The cationic photocuring systems are not susceptible to the effect of oxygen inhibition. However, the limitation of cationic light curing process is that it requires a long curing time. Originality/value The coatings prepared via the UV curing approach can provide superior antismudge effects, and thus they are promising candidates for use in various industries, especially in fields such as antismudge coatings and antigraffiti coatings.
