聚偏氟乙烯膜表面接枝改性的研究进展

Research progress on surface grafting modifications of polyvinylidene fluoride membranes

以近年来聚偏氟乙烯膜表面接枝改性的技术及研究进展为重点,从光引发、等离子体诱导、辐照引发、臭氧活化、化学引发等方面出发,较为系统地探讨了接枝诱发因素对膜表面接枝的影响,简要介绍了接枝改性膜在水处理、工业燃料电池、生物医学等领域的一些应用,并提出了其未来研究趋势.

This paper mainly focused on the technologies and research development on surface grafting modifications of polyvinylidene fluoride membranes recently, systematically discussed the effects of various grafting factors on membrane surface grafting results, particularly involved in those typical grafting methods such as photo initiation, plasma induced, irradiation, ozone activation and chemical initiation. The paper briefly introduced some applications of the grafting modified membranes in water treatment, industrial fuel cell and biomedicine,etc, and the further research trends were also proposed.
