Abstract

This study presents a systematic optimization of ZnO@KH570@CFC/CIP@BPF (ZKCCB) composites through an integrated multi-scale modification strategy, employing response surface methodology (RSM) coupled with Box-Behnken Design (BBD) to enhance their electromagnetic interference (EMI) shielding performance. By tailoring the concentrations of ZnO, CIP, and KH570 components, the optimized composites exhibit exceptional EMI shielding effectiveness (average SE_T = 53.15 dB in the X-band) alongside improved mechanical properties. The interfacial engineering synergistically enhance wave absorption and reflection mechanisms, while RSM enables robust modeling and performance maximization. This work not only establishes a theoretical-practical framework for advanced EMI shielding materials but also proposes a generalizable modification strategy applicable to diverse composite systems. © 2026.
