摘要

Abstract

Poly(phenylene oxide) (PPO)

an engineering plastic with excellent comprehensive performance

faces significant processing challenges owing to its high melt viscosity

which severely limits its large-scale applications. The introduction of polyamide 6 (PA6) effectively improved its processability

but inevitably compromised the inherent heat resistance of PPO. In this study

high-modulus

heat-resistant

and electromagnetically shielded carbon fiber (CF)-reinforced PPO/PA6 (PPO/PA6/CF) microcellular composites were fabricated using chemical foaming injection molding. The effects of CF content on the foaming behavior

thermal properties

mechanical properties

and electromagnetic interference (EMI) shielding performance of the composites were systematically investigated. The results indicated that when the CF content was 5 wt%

the PPO/PA6/CF microcellular composite exhibited the optimal cell structure with an average cell diameter of 49.44 μm and a cell density of 3.48×10

cells/cm

. In addition

the synergistic effect of the fiber network structure and improved crystallinity significantly enhanced the heat resistance of the PPO/PA6/CF foams. Compared with the PPO/PA6 foam

the PPO/PA6/CF foams exhibited an increase in heat deflection temperature (HDT) of 84.7 °C

reaching 181.2 °C

along with a flexural modulus as high as 8509 .16 MPa and an EMI shielding effectiveness of 37.02 dB

demonstrating remarkable multifunctionality. This study provides a feasible pathway for the efficient and scalable production of lightweight PPO-based composites with superior thermal deformation resistance and EMI shielding performance.
