摘要:

聚氯乙烯(PVC)是世界上应用最广泛的塑料之一,因其具有化学和机械特性优异、廉价易得等优点而广泛应用于医疗器械制造、建筑、食品和电子等行业。PVC对水的接触角为90°,而在生物医学和金属防腐蚀等领域的应用中,需要PVC达到超疏水性能。因此,PVC基超疏水材料的需求也变得愈加迫切。本文综述了聚氯乙烯基超疏水材料的分类、制备方法和应用领域,对比了不同种类、不同制备方法的聚氯乙烯基超疏水材料的疏水性能优劣,总结出目前该领域的一些问题,主要包括制备工艺仅限于实验室操作、材料的耐磨耐久性及机械强度有待考察等,并指出该领域的发展方向:①开发简单、环保、低成本的大规模制备工艺;②克服PVC材料热、光稳定性差的弱点,发扬其耐腐蚀性好、机械强度高的优点,进一步扩大材料的应用范围。

Abstract:

Polyvinyl chloride (PVC) is one of the most widely used plastics in the world because of its excellent chemical and mechanical characteristics, the advantages of cheap accessible and widely used in medical equipment manufacturing, construction, food and electronic industries. PVC has a contact angle of 90° to water and is required to achieve superhydrophobic properties in applications such as biomedical and metal corrosion prevention. Therefore, the demand for PVC-based superhydrophobic materials has become increasingly urgent. In this paper, the classification, preparation methods and application fields of PVC-based superhydrophobic materials are reviewed. The different types, different preparation methods of hydrophobic performance of polyvinyl chloride based superhydrophobic material are compared. Finally, some problems of this field are summarized, mainly including that the preparation process is limited to laboratory operations, and the wear resistance, durability and mechanical strength of the materials need to be investigated, etc. The development direction of this field is pointed out: ①developing a simple, environmentally friendly, low-cost large-scale preparation processes; ②overcoming the weak points of poor thermal and light stability of PVC materials, carrying forward its advantages of good corrosion resistance and high mechanical strength, and further expanding the application range of PVC materials.

Key words: polyvinyl chloride, superhydrophobic, preparation, application, coating
