Problems solved by technology

However, since α-ZrP is a hydrophilic inorganic compound, it has poor compatibility with hydrophobic polymers and is difficult to uniformly disperse in the polymer matrix, which makes it difficult to use and process (spinning, injection molding, etc.). At the same time, also cannot function effectively in polymer modification
[0003] At present, the polymer / α-ZrP composite fiber material is mainly prepared by a blending method, and there are unfavorable conditions such as difficult dispersion of zirconium phosphate, single functional component, poor functional effect, poor spinnability, and low fiber strength. A polymer-organically modified and loaded metal ion α-ZrP composite fiber material can effectively solve the above problems
