Ramie fiber yarn (PRF), characterized by its superior microwave transmittance (MWT), is a novel material that can effectively substitute traditional glass (D-GF) in the fabrication of composites for communication equipment shells. However, super hydrophilicity and inadequate thermal conductivity (λ) PRF hinder overall performance safety use. To date, no effective strategy has been developed to prepare multifunctional PRF-reinforced composites, including high hydrophobicity, MWT, λ. Herein, integrating template method with vacuum-assisted spraying technology, mosquito-eye-like honeycomb network was constructed on surface fabric. This network, composed nacre-like brick-and-mortar microstructures as fundamental units, achieves both mesoscopic microscopic order. The biomimetic microstructure enable fabric transition from superhydrophilic high-hydrophobic, significantly reducing water absorption levels similar D-GF-reinforced composites. Furthermore, structures are incorporated into composite interface via surface, resulting MWT λ values up 98% 1.0582 W/mK, respectively. Importantly, waste be fully transformed particles, thereby enabling closed-loop recycling reuse. offer an efficient versatile modification
