项目摘要

Poly (vinylidene fluoride) (PVDF) hollow fiber membrane was prepared from PVDF/diethyl phthalate system via thermally induced phase separation (TIPS). The melting temperature greatly affected the membrane structure. When the melting temperature was 180℃, spherulite structure due to the polymer crystallization was obtained, while the inter-connected structure (lacy structure) was formed at 150℃. The formation mechanism of the membrane structure was discussed based on the DSC data. The spherulite structure showed the higher water permeability with the lower mechanical strength. On the other hand, the inter-connected structure showed the fairly high strength. The effect of the addition of clay on the membrane performance was also investigated. The addition of clay was useful to form inter-connected structure. The resultant hollow fiber membrane had higher membrane strength and membrane elongation.PVB-TiO_2 composite hollow fiber membranes were prepared via nonsolvent induced phase separation (NIPS) method. Titanium dioxide (TiO_2) particle has the property that makes the surface to be hydrophilic by the irradiation of ultraviolet (UV). Though the water permeability for membranes hardly changed with the addition of TiO_2, the tensile strength and elasticity increased. When PVB concentration is 10wt%, the weight ratio of TiO_2 to PVB changed from 1 to 2. The water permeability increased with the increase of TiO_2 content. Furthermore, for all the membranes, with the elapse of time, the water permeability increased, and it became to be constant after about 15days. On the other hand, tensile strength and elasticity kept constant with the elapse of time. In addition, for PVB-TiO_2 membrane, the water contact angle on the membrane surface decreased after the irradiation of UV, which means that the surface of the composite membrane became to be more hydrophilic.
以聚偏氟乙烯(PVDF)/邻苯二甲酸二乙酯(PVDF)为原料,通过热诱导相分离(TIPS)法制备了PVDF中空纤维膜。熔融温度对膜结构有很大影响。熔融温度为180℃时,聚合物结晶形成球晶结构,150℃时形成互连结构(花边结构)。根据DSC数据,对膜结构的形成机理进行了探讨。球晶结构表现出较高的透水性和较低的机械强度。另一方面,连通结构显示出较高的强度。同时考察了粘土的加入对膜性能的影响。粘土的加入有利于形成相互连接的结构。制备的中空纤维膜具有较高的膜强度和膜伸长率。采用无溶剂诱导相分离法制备了PVB-TiO2复合中空纤维膜。二氧化钛(TiO_2)粒子具有在紫外线(UV)照射下使其表面亲水性的特性。虽然膜的透水率随二氧化钛的加入而变化不大,但拉伸强度和弹性有所提高。当PVB质量分数为10wt%时,TiO2与PVB的质量比由1变为2,透水率随TiO2含量的增加而增大。此外,对于所有的膜,随着时间的推移,水的透过率增加,大约15天后变得恒定。另一方面,抗拉强度和弹性随时间保持不变。此外,PVB-TiO2膜经紫外光照射后,膜表面的水接触角减小,说明复合膜的表面亲水性增强。
