用偶联剂-γ(甲基丙烯酰氧)丙基三甲氧基硅烷表面改性后的表面负载有乙烯基官能团活化的纳米氧化锌与苯乙烯在BPO热引发体系下进行接枝共聚,采用红外光谱、热失重和电子扫描显微镜对产物进行表征.实验表明苯乙烯成功地接枝到了活化后的纳米氧化锌表面上,当纳米氧化锌的用量为苯乙烯1%~8%(质量分数)时,纳米氧化锌的用量为苯乙烯4%(质量分数)左右时接枝率最高.
With the coupling agent -γ (methacryloyloxy) propyltrimethoxysilane surface modification of the surface loaded with vinyl-functional activated nano-zinc oxide and styrene in the BPO thermal initiator system graft copolymerization using FTIR, FT-IR and SEM were used to characterize the product.The experimental results showed that styrene was successfully grafted onto the surface of activated nano-ZnO, and when the amount of nano-ZnO was 1% -8% (mass fraction) , When the amount of nano-ZnO is about 4% (mass fraction), the grafting rate is the highest.
