摘要： The objective of this work was to assess and verify the potential loss in composite structure, surface properties, structural strength, and thermal stability of pigmented wood-plastic composites under seawater corrosion conditions. For this purpose, three types of inorganic pigments were utilized and incorporated into a wheat straw fiber-reinforced polyvinyl chloride (PVC) composite. These pigments are: an iron oxide red, an iron oxide yellow, and an iron oxide blue (i.e., three fine-arts primary colors). An artificial seawater accelerated corrosion experiment was carried out. The results show that wheat straw fiber-reinforced PVC composites pigmented with iron oxide pigment have better seawater corrosion resistance, including better fiber/matrix interfacial interaction, lower total discoloration, and higher surface hydrophobicity, mechanical properties, and thermal stability. From these results, positive relationships between inorganic pigments and service reliability are confirmed for wood-plastic composites under seawater corrosion conditions.
