石墨烯改性熔喷聚丙烯非织造材料及其吸附性能

以甲基丙烯酸丁酯(BMA)为单体,过氧化苯甲酰(BPO)为引发剂,对GO进行功能化,将功能化氧化石墨烯(GO)接枝到熔喷聚丙烯非织造材料(MBPP)表面,然后将氧化石墨烯还原,制得石墨烯改性熔喷聚丙烯非织造材料(RGO-MBPP)。通过FTIR、Raman和SEM表征了RGO-MBPP的结构,并考察了RGO-MBPP的饱和吸油率、保油率和重复使用率。结果表明:石墨烯附着在MBPP纤维表面;MBPP的饱和吸油率为29.65g/g,当氧化石墨烯的质量浓度为1.0 g/L、BMA用量为3 m L时,得到RGO-MBPP饱和吸油率可达34.66 g/g。RGO-MBPP使用5次的饱和吸油率分别为34.39、34.10、34.73、35.29、31.72 g/g,表明RGO-MBPP重复使用4次后仍具有良好的吸附性能。

Graphene Modified Melt Blown Polypropylene Nonwovens and their Adsorption Properties

The melt blown polypropylene nonwovens (MBPP) as the substrate, butyl methacrylate (BMA) as a transitional body (BPO) benzoyl peroxide as initiator grafted graphene oxide(GO), and the ascorbic acid reduction reduction of graphene oxide, preparation of graphene modified PP meltblown non weaving material. By using scanning electron microscopy (SEM) Fu Liye, elemental analysis, infrared spectroscopy (FTIR), Raman spectroscopy analysis and characterization of modified polypropylene meltblown nonwovens and its absorption properties were tested. The results show that the saturated oil absorption rate increased from 29.65g/g to 34.66g/g, graphene modified material meltblown polypropylene nonwoven after oil retention and reuse the rate was almost not affected.
