초록

The excessive accumulation of sulfur from industrial processes poses a significantenvironmental challenge, contributing to acid rain, air pollution, and soil contamination.
While managing this surplus sulfur is challenging, it has the potential to berepurposed into sustainable materials through proper utilization. This study introduces anovel approach to sulfur management by employing elemental sulfur as a reducing agentto synthesize sulfur-doped reduced graphene oxide (S-rGO). The S-rGO was incorporatedinto a porous polyimide (PPI) matrix to create a high-performance composite withenhanced flame retardancy, thermal stability, and tailored porosity. Comprehensive characterizationrevealed that sulfur doping introduced structural defects, which contributedto the material's improved functional properties. Additionally, the porosity in the PPI/S-rGOcomposite, combined with varying filler contents, enhanced thermal stability, dynamicstorage modulus, and flame retardancy. This work provides a sustainable solution for sulfurmanagement and presents a multifunctional material suitable for applications in industriesrequiring flame-retardant, thermally stable, and porous polymers, such as semiconductorcoatings and battery separators.
