Abstract: In this study, a compound anti-mold agent IPBC/DDAC and an ultraviolet absorber UV1130 were used to enhance the weatherability of bamboo/polypropylene carbonate (PPC) composites exposed outdoors. The samples were evaluated by mechanical test, surface color difference analysis, anti-ageing test and mold resistance test. The results indicated that the appropriate addition of IPBC/DDAC and UV1130 effectively mitigated the decline in tensile strength and flexural strength caused by changes in environmental factors; however, their impact on the variation in impact strength was not as significant. At the same level of IPBC/DDAC modification, the higher contents of the UV1130 introduction into the composites, the better surface color stability could be obtained. The introduction of appropriate amount of IPBC/DDAC and UV1130 can effectively improve the mold resistance, water vapor and thermal resistance of bamboo/PPC composite, in which the water vapor resistant level could be up to Grade 5, and no obvious cracks or bubbling were observed on the surface of the composites; the anti-mold efficiency of the composites could be above 90%.
