表面活性剂对聚乙烯醇基薄膜透光性及机理的影响

文章导读

摘要针对聚乙烯醇（PVA）与表面活性剂能组成复配体系，制备了聚乙烯醇基亲水性薄膜材料，研究了表面活性剂的掺量对聚乙烯醇基薄膜的微观结构、孔隙度、透光性能、PVA结晶度及晶粒尺寸的影响。采用紫外分光光度计考察了各薄膜的透光性；采用扫描电子显微镜观察了聚乙烯醇/表面活性剂的横截面微观结构；采用X射线衍射仪考察了不同表面活性剂的添加量对复合薄膜的晶相组成及PVA晶粒尺寸的影响，结果表明当表面活性剂添加量在6%~10%（质量分数，下同）时，阳离子表面活性剂十六烷基三甲基溴化铵（CTAB）明显地降低聚乙烯醇的结晶度，而阴离子表面活性剂十二烷基苯磺酸钠（SDBS）则没有此效果；CTAB的加入使聚乙烯醇/CTAB体系中PVA晶粒尺寸增大，SDBS的加入使聚乙烯醇/SDBS体系中PVA晶粒尺寸减小。最后对聚乙烯醇与表面活性剂相互作用机理示意图进行了预测。

Abstract： The polyvinyl alcohol (PVA) hydrophilic thin film was prepared by combining PVA with surfactants. The effects of surfactants content on microstructure, porosity, light transmittance, PVA crystallinity and crystallite size of PVA thin films were studied. The light transmittance of each film was investigated by ultraviolet spectrophotometer. The cross section microstructure of polyvinyl alcohol/surfactants was observed by scanning electron microscope. The effect of the different surfactant contents on the crystal phase composition and PVA crystallite size of the composite film was researched by X-ray diffraction. The results show that when the amount of surfactant is between 6% to 10%(mass fraction), cationic surfactant cetyl trimethyl ammonium bromide (CTAB) obviously reduces the crystallinity of polyvinyl alcohol, but anionic surfactant sodium dodecyl benzene (SDBS) sulfonate doesn't have this effect; the addition of CTAB increases the crystallite size of PVA in PVA/CTAB systems, while the addition of SDBS decreases the crystallite size of PVA in PVA/SDBS systems. Finally, the schematic diagram of the interaction mechanism between polyvinyl alcohol and surfactants is predicted.
