Polyphosphazene microsphere as well as preparation method, and application and implementation method thereof

Abstract

The invention relates to a polyphosphazene microsphere as well as a preparation method and an application thereof in the technical field of materials. The polyphosphazene microsphere has the structural formula as disclosed in the specification. The preparation method of the polyphosphazene microsphere comprises the following steps of: (1) in the presence of an acid binding agent and an organic solvent, carrying out polycondensation reaction on hexachlorocyclotriphosphazene and bisphenol AF to obtain a solution; (2) and filtering the solution, washing a filtering medium, and drying to obtain the polyphosphazene microsphere. The invention also relates to application of the polyphosphazene microsphere in the preparation of a super-hydrophobic surface. The polyphosphazene microsphere has the advantages of low cost, excellent thermostability, flame retardance, chemical durability and radiation resistance. The preparation method has the advantages of short time, mild reaction conditions and simple process. The super-hydrophobic surface prepared from the polyphosphazene microsphere has excellent super-hydrophobicity.

Description

technical field The invention relates to a microsphere in the technical field of materials and a preparation method, use and realization method thereof, in particular to a polyphosphazene microsphere and a preparation method, use and realization method thereof. Background technique Surfaces with a water contact angle >150° are called superhydrophobic surfaces. Since its recognition in the 1940s, superhydrophobic surfaces have attracted widespread attention and have been widely used in self-cleaning materials, antifouling materials, and water-repellent materials. Many organisms in nature exhibit interesting superhydrophobic phenomena, such as water mosquitoes, geckos and lotus leaves. Especially for lotus leaves, studies have shown that its superhydrophobicity is the result of the combined action of the micro / nano secondary structure on the surface of lotus leaves and the waxy low surface energy substances on the surface. Inspired by this basic principle, artificial supe...
