摘要

使用3种不同结构的离子表面活性剂分别对纳米蒙脱土(MMT)进行有机化修饰，再通过原位聚合法合成了一系列聚乙烯醇缩丁醛/有机蒙脱土(PVB/OMMT)复合材料。傅里叶红外光谱(FTIR)和能量散射光谱(EDS)分析结果表明，离子表面活性剂确实对纳米蒙脱土实现了插层作用，成功制备了有机蒙脱土。X射线衍射(XRD)分析表明，改性后离子表面活性剂成功插入纳米蒙脱土，使蒙脱土的层间距增大。水接触角测试结果表明，改性后纳米蒙脱土的表面极性发生改变，疏水性提高，其与PVB分子链的相容性得到一定的改善。力学性能和光学性能测试结果显示，当PVB/OMMT复合材料中分别添加0.15 wt%的十六烷基三甲基溴化铵(CTAB)、0.20 wt%的

-二甲基-

-辛癸基-1-十八胺鎓氯化物(DDA)以及0.15 wt%的椰油酰胺丙基甜菜碱(CPB)修饰的纳米蒙脱土(CTAB-MMT、DDA-MMT、CPB-MMT)时，其拉伸强度分别显著提升了23.25%、30.23%和33.69%，同时该复合材料保持高可见光透过率和良好的紫外屏蔽性能。体积电阻率测试表明，MMT/OMMT的引入能有效提高PVB基纳米复合材料的体积电阻率，增强其绝缘性能。

Abstract

Three different ionic surfactant structures were used to organically modify nano-montmorillo

nite (MMT)

followed by the synthesis of a series of poly(vinyl butyral)/organically modified montmorillonite (PVB/OMMT) composites through

in situ

polymerization. The Fourier transform infrared spectroscopy (FTIR) and energy dispersive spectrometer (EDS) analyses indicated that the ionic surfactants achieved intercalation within the nano-montmorillonite

successfully preparing the organically modified montmorillonite. The X-ray diffractomete (XRD) analysis demonstrated that the modified ionic surfactants were successfully intercalated into the nano-montmorillonite

resulting in an increased interlayer spacing. Water contact angle tests showed that the surface polarity of the modified nano-montmorillonite changed

with improved hydrophobicity and a certain degree of enhanced compatibility with PVB molecular chains. Mechanical and optical property tests revealed that when the addition levels of nano-montmorillonite modified with cetyltrimethylammonium bromide (CTAB)

dimethyl di(hydrogenated tallow) ammonium chloride (DDA)

and cocamidopropyl betaine (CPB) (CTAB-MMT

DDA-MMT

and CPB-MMT) were 0.15 wt%

0.20 wt%

and 0.15 wt%

respectively

the tensile strength of the PVB/OMMT composites was maximally enhanced by 23.25%

30.23%

and 33.69%

respectively

while maintaining high visible light transmittance and good ultraviolet (UV) shielding effects. Volume resistivity tests indicated that the introduction of MMT/OMMT could effectively increase the volume resistivity of the PVB-based nanocomposites

enhancing their insulating properties.
