降冰片烯基硅烷偶联剂改性高岭土/聚双环戊二烯复合材料的制备OA
Preparation of kaolin/polydicyclopentadiene composites modified with norbornene-based silane coupling agent
设计合成了两种易于获得的降冰片烯基硅烷偶联剂(NMKSC、NHKSC)用于改性高岭土,并制备了降冰片烯基高岭土/聚双环戊二烯(PDCPD)复合材料.结果表明,降冰片烯基高岭土可在双环戊二烯中良好分散,同时所得降冰片烯基高岭土/PDCPD复合材料的冲击韧性可提升225%,拉伸强度和弯曲强度可提高约10%.这些降冰片烯基高岭土/PDCPD复合材料玻璃化转变温度可提升至160℃,表现出良好的热稳定性.
Two readily synthesizable norbornene-based silane coupling agents(NMKSC and NHKSC)were designed and synthesized to modify kaolin,leading to the successful preparation of norbornene-based kaolin/polydicyclopentadiene(PDCPD)composites.The modified kaolin demonstrated excellent dispersion within the dicyclopentadiene monomer.Compared to unmodified PDCPD,the resulting composites exhibited a remarkable increase in impact toughness of up to 225%,alongside approximately 10%improvements in both tensile and flexural strength.Furthermore,the composites maintained good thermal stability.
