1、第27卷第2期CHEM●一ICA'LR?ESEuARCH1http：／／hxya．cbpt．cnki．net雙馬來酰亞胺樹脂／Sio2納米復(fù)合材料的制備及性能柳準(zhǔn)，趙夢(mèng)溪，孫闖，徐啟杰(黃淮學(xué)院化學(xué)化工系，河南駐馬店463000)摘要：以表面含有胺基官能團(tuán)的納米SiO為填料，通過一步原位聚合法制備雙馬來酰亞胺樹]~／SiO納米復(fù)合材料(BMI／SiOz)．采用熱重分析儀(TGA)、紅外光譜分析儀(FTIR)、邵氏D硬度計(jì)(H)等儀器設(shè)備對(duì)BMI／SiOz納米復(fù)合材料進(jìn)行測(cè)試分析，探討納米SiOz對(duì)雙馬來酰亞胺聚酯樹脂的熱穩(wěn)定性能、硬度和界面強(qiáng)度的影響．
2、結(jié)果表明，所制備的BMI／SiOz納米復(fù)合材料的硬度隨加入的納米Si0含量的增加，呈現(xiàn)逐漸升高趨勢(shì)．當(dāng)納米SiOz含量為3時(shí)，相對(duì)于雙馬來酰亞胺聚酯，復(fù)合材料的硬度提高了8o．通過熱穩(wěn)定性分析可知，納米SiOz的加入降低了雙馬來酰亞胺樹脂基體材料的熱分解溫度，使其從458℃降低到451℃．通過對(duì)雙馬來酰亞胺／Si0z納米復(fù)合材料的界面分析發(fā)現(xiàn)，納米si0z的表面接枝了雙馬來酰亞胺分子鏈，說明納米SiOz參與了雙馬來酰亞胺的聚合過程，有利于提高聚合物基體材料與填料間的界面強(qiáng)度，進(jìn)而提高復(fù)合材料的機(jī)械性能．關(guān)鍵詞：原位聚合；納米復(fù)合材料；力學(xué)性能；硬度；納
