摘要
利用硅烷偶联剂(LM-N308)对纳米凹凸棒石表面进行有机改性。红外光谱和高分辨透射电镜照片表明,约有占改性产品质量6.1%的LM-N308以化学键的形式结合在在纳米凹凸棒石的表面,形成有机包覆层。表面改性后的纳米凹凸棒石的表面性质由亲水性变成了疏水性,用于复合材料中能同时提高其强度和韧性。
Organic surface modification of nano-attapulgite with silane coupling reagent LM-N308 was studied. According to the results of FTIR and HRTEM, it was inferred that the LM-N308 was bound with about 6. 1% on the surface of nano-attapulgite particles, and an organic coating layer also formed. The surface property of nano-attapulgite modified with LM-N308 was changed from hydrophilicity to hydrophobicity, and the strength and toughness of the composite material was improved by adding modified nano-attapulgite.
