蝌蚪型POSS嵌段共聚物多孔膜制备及其疏水性能
Preparation and its hydrophobic property of tadpole POSS block copolymer porous film
摘要
Abstract
Aiming at the disadvantages of traditional hydrophobic modified methods,such as higher temperature treatment,higher equipment requirements,and lower inherent properties of the fabric,the tadpole type polyhedral oligomeric silsesquioxane(POSS)block copolymer was used as the film forming material,and the orderly porous films were prepared by breath figure method.The porous film with uniform pore size was prepared base on silicon wafer by optimizing the solvent type,copolymer concentration,film forming temperature and film forming time,then its surface hydrophobic property was tested.Using cotton fabric as substrate,porous film was prepared by optimizing copolymer concentration,and its surface hydrophobic property was tested.The results showed that the optimum conditions for film formation of tadpole type block copolymer on the surface of silicon wafer were as follows:chloroform as solvent,30 mg/mL copolymer concentration,80℃temperature and 60 s time.Under the conditions,the water contact angle of porous film was 117.8°,and the hydrophobic property was achieved.The porous structures were prepared with cotton fabric as basis through breath figure method.When the copolymer concentration was 60 mg/mL,the water contact angle was 154.0°.The structure of pores was uniform with superhydrophobic property.Compared with the dipping-drying method,the water contact angle was about 15° higher at the same concentration.关键词
