Abstract The development of multifunctional bio‐adhesives that are electrically conductive, flame‐retardant, and electromagnetic shielding is crucial for advancing next‐generation wood‐based composites. However, to date it remains a significant challenge achieve such functionalities in adhesives while maintaining their strong adhesion. This study draws inspirations from the microstructure properties coral shells, proposed multiphase engineering prepare soy protein isolate (SPI) adhesive (SPI/PA@G) by introducing hierarchical polyaniline/phenylphosphonic acid aggregates‐loaded graphene nanoplatelets (GNPs) hybrid. Because presence aggregates, designed SPI/PA@G exhibits remarkable flame retardancy with high limiting oxygen index value ≈39.4%. GNPs form highly conductive network on wood particles surfaces, as‐prepared composite achieves an electrical conductivity as 43100 S m −1 , gives rise effectiveness 52.1 dB. In addition, multiple crosslinking interactions endow excellent bonding strength, reflected flexural strength 19.7 MPa composite. offers new approach design advanced composites, which holds great potential real‐world applications creating functional wooden products beyond.
