“…The cured epoxy exhibited excellent thermal stability, thermal conductivity, and outstanding dielectric properties. Similarly, Meng and colleagues [ 19 ] obtained two epoxy monomers with furan structures from honokiol and catechol. An epoxy resin with interpenetrating network structure was prepared by mixing and curing the two monomers.…”

In order to explore more sustainable epoxy resins, a series of novel bio‐based epoxy resins with long silicone‐chain (SIHOEP) were synthesized from honokiol. First, honokiol epoxy was synthesized from honokiol. Then, the hydrogen‐containing siloxane (HS) was copolymerized with honokiol epoxy, and the bio‐based epoxy resins with long silicone‐chain were prepared through the hydrosilylation reaction. Before curing with methyl hexahydrophthalic anhydride (MHHPA), the structure of SIHOEP was confirmed by Fourier‐transform infrared spectroscopy (FTIR) and nuclear magnetic resonance spectroscopy (1H NMR). The molecular weight of SIHOEP was analyzed by gel permeation chromatography (GPC). The results showed that the toughness of SIHOEP‐MHHPA was enhanced after curing, the maximum elongation at break reached 45.75%, and the glass transition temperature (Tg) was up to 92.9 °C. Long silicone‐chain segment could enhance the toughness of bio‐based epoxy. By adjusting the hydrogen content of long‐chain hydrogen‐containing siloxane and the reaction ratio, the overall performance of bio‐based epoxy silicone resins can be effectively controlled, which provides a valuable guide for the design of bio‐based epoxy materials with excellent mechanical properties. Meanwhile, the curing kinetics of bio‐based silicone/epoxy hybrid resins with methyl hexahydrophthalic anhydride (MHHPA) as curing agent was studied.This article is protected by copyright.
