Abstract

In this study, wood–plastic composites (WPCs) were prepared from polyvinyl chloride (PVC) modified by sodium trisulfide (Na₂S₃) and rice straw (RS) treated with 7% sodium hydroxide solution. The results showed that after modification, 35.4 wt. % of sulfur is present in the structure of PVC containing sulfur (PVCS). The structural, morphological, thermal, and mechanical properties of the samples were investigated. As the RS fibers content in the composites increased, the thermal stability also increased but the mechanical properties decreased slightly. Moreover, the presence of sulfur in the matrix created antifungal properties that the results showed us that the PVCS can inhibit and kill Aspergillus niger and Aspergillus brasiliensis. Also, graphene oxide (GO) was added to the matrix to improve its properties. The addition of GO to composite improved the mechanical and thermal properties to extent that its mechanical properties were better than the sample without RS.

有针对性地应用氧化石墨烯改善PVCS/RS复合材料的力学和热性能

在本研究中，以三硫化钠（Na2S3）改性的聚氯乙烯（PVC）和7%氢氧化钠溶液处理的稻草（RS）为原料制备了木塑复合材料（WPCs）。结果表明，改性后，35.4 重量%的硫存在于含硫PVC（PVCS）的结构中。对样品的结构、形态、热性能和力学性能进行了研究。随着RS纤维含量的增加，复合材料的热稳定性也有所提高，但力学性能略有下降。此外，基质中硫的存在产生了抗真菌特性，结果表明PVCS可以抑制和杀死黑曲霉和巴西曲霉。此外，还将氧化石墨烯（GO）添加到基体中以改善其性能。在复合材料中加入GO可以改善复合材料的力学性能和热性能，其力学性能优于未加入RS的样品。
