Polypropylene (PP) foam is a potential high-temperature insulating porous material with high mechanical properties and service temperature. However, the development of multifunctional foams based on PP still faces challenges. In this study, grafting by ultraviolet (UV) radiation was successfully used to introduce ester-based groups into molecular chains. The grafted product then blended pure in specified proportion pelletized, subjected chemical foaming obtain modified rigid foams. effectively reduced melt flow rate heterogeneous nucleation during foaming, improved efficiency, promoted formation nanometer- micron-sized cells. newly introduced also absorbed near- far-infrared radiative energy; meanwhile, cells enhanced Knudsen Phonon Scattering Effects, resulting significant reduction thermal conductivity, from 186.7 65.3 mW/(m·K). Moreover, obtained exhibited well hydrophobic under complex environmental conditions. multiscale demonstrated simultaneous heat transfer coefficient, solid gas thereby providing new strategy for further reducing conductivity polymer-based achieving excellent insulation. This work realized preparation difficult-to-make foams, laying foundation diversification expanding their application areas.
