大分子受阻酚功能化碳纳米管改性聚氨酯网状泡沫塑料的制备及性能研究OA北大核心CSTPCD
Preparation and Property study of Polyurethane Reticulated Foam Modified by Macromolecular Hindered Phenol Functionalized Carbon Nanotubes
以γ-氨丙基三甲氧基硅烷(APTMS)修饰的碳纳米管(CNTs)为载体,通过表面引发氧化-还原聚合接枝聚甲基丙烯酸羟乙酯(CNTs-PHEMA),再经酯化反应接枝3,5-二叔丁基-4-羟基苯甲酸(CNTs-PHEMA-g-AO-e),最后以此改性聚氨酯(PU)网状泡沫塑料详细研究了CNTs-PHEMA-g-AO-e对PU网状泡沫塑料表观密度、力学、抗静电和耐老化性能的影响.结果表明:通过表面引发氧化-还原聚合和酯化反应成功制得AO-e接枝率为8%…查看全部>>
Poly(2-hydroxyethyl methacrylate)(PHEMA)was grafted onto γ-aminopropyl trimethoxysilane(APTMS)functionalized carbon nanotubes(CNTs)by surface-initiated oxidation-reduction polymerization.Then 3,5-di-tert-butyl-4-hydroxybenzoic acid(CNTs-PHEMA-g-AO-e)was grafted by esterification.The effects of CNTs-PHEMA-g-AO-e on the apparent density,mechanical properties,antistatic and aging resistance of polyurethane(PU)reticulated foam were studied in detail.The results …查看全部>>
