Abstract：Introducing hydrophilic additives is an effective method to improve the structure and permeation performance of polyvinylidene fluoride （PVDF） membranes.In this work,oxidized multiwall carbon nanotubes （OMWNTs） accompanied with polyethylene glycol/polyvinyl pyrrolidone （PEG/PVP） additives were employed to modify PVDF membranes.The effects of additives on the structure,permeation performances,hydrophilicity and crystallization behavior of the prepared PVDF membranes were investigated in detail.The results indicate that the addition of OMWNTs can enhance the permeation flux,hydrophilicity and mechanical property of PVDF membranes.The pure water flux（PWF） attains 222.9±12.5 L·m-2·h-1·bar-1 and 256.9±14.8 L·m-2·h-1·bar-1 by adding 0.6 wt.% OMWNTs accompanied with 5% PEG 200 and 3% PVP in the cast solution,respectively.PEG200 additive can enhance the dispersion of OMWNTs,and accelerate the exchange rate between solvent and nonsolvent.PVP working as poreforming agent promotes the growth of pores of PVDF membranes and pure water permeation flux.

1 Introduction
In the recent years,polyvinylidene fluoride （PVDF） has become a very popular material to prepare microfiltration/ultrafiltration（MF/UF） membranes for its superior thermal,chemical stability and oxidation resistance etc.[1-4].However,due to its strong hydrophobicity,PVDF membranes are easily fouled by natural organic matters （NOMs）,proteins and other substances.To overcome the shortcomings,various ways were explored to modify PVDF membranes.Among these methods,blending modification is widely used because it makes preparation and modification be accomplished in a single step.And numerous nanofillers were employed to modify PVDF membranes[5-8].
For its high specic surface area,high chemical stability and easy possessing property,multiwall carbon nanotubes （MWNTs） also attracted considerable attentions in membrane field[9].Zhao et al.[10]successfully prepared PVDF/MWNTs membranes and the blending membranes exhibited improved hydrophilicity,pure permeation flux（PWF） and higher bovine serum albumin （BSA） rejection.Ma et al.[11]investigated the effects of oxidized MWNTs （OMWNTs） on PVDF membranes and found that oxygencontaining groups of OMWNTs played a critical role in determining the morphologies and performances of PVDF membranes.However,there are two important issues to retard the application of MWNTs in polymer composites[12].First,it tends to aggregate in the casting solution due to the strong Vander Waals forces.Moreover,smooth surface of CNTs and lack of interfacial bonding will result in weak interfacial adhesion between CNTs and polymer matrix[13].So,lots of works were done to enhance the dispersion and interfacial adhesion[14-16].
