Preparation of CuO/polypropylene/ethylene-octene copolymer composite melt-blown nonwovens and their oil absorption properties

In order to efficiently and economically deal with the pollution caused by oil leakage,the melt-blown nonwoven materials(MB)was prepared by the blending of polypropylene(PP)and ethylene-octene copolymer(POE).The surface of the composite melt-blown nonwoven material was loaded with nano-copper oxide(CuO)for hydrophobic modification.The morphology,structure,water contact angle,oil absorption and mechanical properties of the nonwovens before and after modification were tested.The results show that the deposition of nano CuO causes the crystallinity of CuO/PP/POE composites to decrease,but no significant change in the melting and crystallization temperatures.In addition the deposition of nano CuO resulted in about 1°decrease in the water contact angle,and the hydrophilicity increases slightly.Compared with the pure PP nonwovens,the oil absorption rate of the composite melt-blown nonwovens loaded with nano-CuO is improved.The oil absorption rate of melt-blown nonwovens with POE content of 15%is up to 9.22 g/g for machine oil and 9.4 g/g for silicone oil,and the longitudinal fracture strength is increased,but the elongation at break is decreased.
