Preparation and Durability Study of Anti corrosion Polyethylene Composite Materials
External factors such as irradiation and light can cause the molecular chain of high density polyethylene(HDPE)to break and reduce its inherent properties.Therefore,improving the durability and corrosion resistance of HDPE is of great significance for expanding its application.In view of this situation,HDPE/m-CNT composites with high durability were prepared by using nitric acid modified carbon nanotubes(m-CNT)as fillers,and their mechanical properties and durability were studied.The results showed that the mechanical properties of HDPE/m-CNT composites were significantly increased due to the bridging effect of m-CNT on the matrix,and reached the maximum value in HDPE/m-CNT-3.In the photothermal durability,the tensile strength and compressive strength of HDPE/m-CNT-3 decreased by only 5.5%and 2.1%after 96 h aging,showing the best durability.Therefore,the above results show that the addition of m-CNT can effectively enhance the durability of HDPE composites.
