Abstract

An epoxy-phenolic network is modified with hyperbranched polysiloxane (HBPSi). The addition of HBPSi-2, which has medium molecular weight, can significantly decrease the viscosity of the uncured epoxy-phenolic system and increase the crosslinking density and homogeneity of the cured crosslinking network. With 10% HBPSi-2, the mechanical properties of the samples are improved comprehensively: tensile modulus and maximum strength increase by 11.4% and 36.2%, respectively, while elongation at break and impact strength increase by 153.8% and 186.7%, respectively. The comprehensive improvements in the mechanical properties are attributed to combined effects of crosslinking density, network rigidity, cohesive density and the matrix-modifier compatibility. What is more, HBPSi-2 also significantly increases the char yield of the material and decreases the thermal weight loss rate, indicating an improved thermal stability. All these results may provide a new strategy for toughness and strength improvement of the epoxy-phenolic network.

摘要

用超支化聚硅氧烷（HBPSi）对环氧-酚醛网络进行改性。添加中等分子量的HBPSi-2可显著降低未固化环氧-酚醛体系的粘度，并提高固化交联网络的交联密度和均匀性。添加10%的HBPSi-2时，样品的力学性能得到全面改善：拉伸模量和最大强度分别提高了11.4%和36.2%，而断裂伸长率和冲击强度分别提高了153.8%和186.7%。力学性能的全面改善归因于交联密度、网络刚性、内聚密度和基体-改性剂相容性的综合作用。此外，HBPSi-2还显著提高了材料的残炭率，降低了热失重率，表明热稳定性得到改善。所有这些结果可能为提高环氧-酚醛网络的韧性和强度提供一种新策略。
