摘要
以聚乙二醇型非离子表面活性剂作为亲水改性剂,与聚氨酯丙烯酸酯预聚体复合,进一步通过紫外光固化等手段制备出仿生鲨鱼皮黏液分泌的超亲水功能表面.研究表明,在光固化聚氨酯体系中引入吐温20(Tween 20)、吐温40(Tween 40)、吐温60(Tween 60)、吐温80(Tween 80)、吐温85(Tween 85)或曲拉通X-100(Triton X100)等亲水改性剂,可获得具有稳定自修复功能的超亲水仿生功能表面,且展示出较好的透光性和防雾与油-水分离效果.该仿生鲨鱼皮黏液分泌超亲水功能表面的制备方法简单有效、绿色环保,为仿生超亲水表面材料的设计和制备提供了新思路,有望用于生物医用涂层、油-水分离及防污涂料等领域.
The skin of sharks exhibit superhydrophilic and underwater superoleophobic properties through the continuous secretion of mucus.Inspired by this,we propose a simple route to create superhydrophilic surface through the introduction of hydrophilic modifiers into the polymer matrix,simulating the secretion of shark skin mucus by means of spontaneous migration of hydrophilic modifiers onto the polymer surface.In this paper,polyethylene glycol type nonionic surfactants were selected as hydrophilic modifiers,which were firstly mixed with polyurethane acrylate prepolymer,after that,the mixture was cured by UV radiation to obtain the bionic functional surface.Research results showed that the introduction of hydrophilic modifiers such as Tween 20,Tween 40,Tween 60,Tween 80 or Triton X100 into the UV-curable polyurethane system can obtain superhydrophilic surface with stable self-repairing function,excellent light transmittance,antifogging and oil-water separation effects.This method is simple,cost-effective,and environmentally friendly,which provides a new idea for the design and preparation of bionic superhydrophilic surface,and therefore,it is expected to be effectively used in biomedical coatings,oil-water separa⁃tion,antifouling coatings,etc.
