AI Technical Summary

Technical Problem

Existing protective materials for high-frequency communication equipment are insufficient in providing high RF transmission, hydrophobicity, and structural integrity, making it difficult to effectively resist the effects of outdoor environments.

Method used

The product employs a multi-layer composite structure, comprising a structural substrate, a multi-layer fluoropolymer film, and a low-melting-point fluoropolymer adhesive layer. By selecting fluoropolymer layers and adhesive layer materials with different melting points, a combination of a high-melting-point fluoropolymer layer and a low-melting-point fluoropolymer adhesive layer is formed, thereby enhancing the protective performance of the material.

Benefits of technology

It achieves high RF transmission, hydrophobicity, and structural integrity in high-frequency communication equipment, effectively protecting the equipment from outdoor environmental influences and improving the overall performance of the materials.

Abstract

This disclosure relates to a composite article comprising: a structural substrate; a multilayer fluoropolymer film, the multilayer fluoropolymer film potentially including a high-melting-point fluoropolymer layer; and a low-melting-point fluoropolymer adhesive layer, the low-melting-point fluoropolymer adhesive layer being in contact with the structural substrate and the fluoropolymer film. The high-melting-point fluoropolymer layer may have a melting temperature A1, and the low-melting-point fluoropolymer adhesive layer may have a melting temperature A2. The melting temperature A2 may be lower than the melting temperature A1.
