| description | The invention provides a cross-linked polyphenylene sulfide microporous material with controllable crystallization, the polyphenylene sulfide microporous material is formed by foaming a base material through a supercritical fluid, and the foamed base material has uniform micron-sized pores; the matrix material is cross-linked polyphenylene sulfide with a long branch chain and a cross-linked network structure, and the matrix material is formed by carrying out thermal oxidation treatment on polyphenylene sulfide with single main chain m-benzene content or by carrying out thermal oxidation treatment on a blend formed by blending polyphenylene sulfide with different main chain m-benzene contents. The polyphenylene sulfide microporous material has low dielectric property and high wave transmission property under the GHz frequency, and on the basis, the invention further provides application of the polyphenylene sulfide microporous material in the field of 5G wave transmission. According to the invention, the probl |
