埃洛石纳米管的磺化改性实验研究

Experimental Study on Sulphonated of HNTs

利用硅烷偶联剂3-(异丁烯酰氧)丙基三甲氧基硅烷(MPS)对埃洛石纳米管(HNTs)改性,得到HNTsMPS,然后通过与苯乙烯(ST)、二乙烯基苯(DVB)的游离基聚合反应引入苯环,借助磺化反应,得到表面含有磺酸根的HNTs-SO3H杂化亚微粒,并对所得微粒做了FTIR、TEM、TGA等分析,且测量其离子交换容量(IEC)。FTIR,TEM,TGA都显示HNTs-SO3H杂化亚微粒成功制备,且IEC为0.258 9 mmol/g(HNTs)。

HNTs modified by silane coupling agent 3-（ methacryloxy） propyl trimethoxysilane（ MPS） to obtain HNTs- MPS is studied. Through a free radical polymerization reaction with styrene and divinyl benzene,we bring benzene into the HNTs- MPS. After that,with the sulfonation reaction,a surface containing sulfonic HNTs- SO3 H hybrid sub- particles is obtained. The particles incomed is analysised about FTIR,TGA and TEM,as well as its ion exchange capacity（ IEC） is tested. The results indicate that HNTs- SO3 H are grafted onto the HNTs successfully,and the IEC is 0. 2589 mmol / g HNTs.
