- Bio‐Derived Hard Carbon from Bassia scoparia as a Multifunctional Reinforcement for Chlorinated Polypropylene: Structural, Thermal, and Bioactive Performance Gokhan Acik Esra Kulaksiz Alayont Burcu Acik Gulcan Kuyucuklu Kazan Derya Altintas Hakan Kolancilar Yuksel Bayrak ChemistryOpen The development of sustainable multifunctional polymer composites with enhanced thermal, mechanical, surface, and bioactive properties is important for advanced coating and packaging applications because conventional polypropylene (PP)‐based materials generally lack intrinsic antioxidant and antibacterial functionality. In this study, nitric acid‐treated hard carbon derived from Bassia scoparia biomass (N‐BSHC) was utilized as a sustainable multifunctional reinforcement for chlorinated polypropylene (PP‐Cl) composite films. Composite films containing 1.0, 1.5, and 2.5 wt% N‐BSHC were fabricated by solution casting and characterized using Fourier transform infrared, scanning electron microscope‐energy‐dispersive X‐ray (SEM‐EDX), water contact angle (WCA), thermogravimetric analysis, differential scanning calorimetry, mechanical testing, and antioxidant and antibacterial assays. SEM‐EDX analysis confirmed homogeneous filler distribution and the presence of oxygen‐ and nitrogen‐containing surface functionalities, which improved matrix compatibility and surface wettability. The WCA decreased from 105° for neat PP‐Cl to 94° for the composite containing 2.5 wt% filler. Thermal degradation temperatures increased from 338°C/421°C to 346°C/428°C, while the elastic modulus increased from 48.56 to 73.61 MPa at 1.5 wt% filler loading. Furthermore, the composites exhibited antioxidant activity and strong antibacterial performance against Staphylococcus aureus and Escherichia coli . These findings demonstrate that biomass‐derived N‐BSHC is an effective sustainable filler for advanced PP‐Cl composites. 10.1002/open.70241 http://creativecommons.org/licenses/by/4.0/
