Abstract

In this work, a polyethylene terephthalate (PET) nonwoven support was prepared by wet-laid and hot-press technology and used as support for separation membranes. The properties of the PET nonwoven support were studied to determine the effect of hot-pressing parameters and PET fiber ratio, and were optimized by response surface methodology. Result showed that the PET nonwoven support with 62% low melting point PET (LPET-180) fibers obtained satisfactory properties and structure after hot pressing at 220 °C under the pressure of 9 MPa for 20 s. The response surface analysis indicated that the temperature and time of hot pressing and the fiber ratio were the most important factors affecting the strength and air permeability of the PET nonwoven support. After hot pressing, the PET nonwoven support exhibited interconnected structure, small pore size, low porosity, and high strength. Then phase inversion technique was applied to prepare a polysulfone (PSF) layer on the PET nonwoven support and an ultra-thin polyamide (PA) active layer was prepared by interfacial polymerization on the PSF layer. The practicality of PET nonwoven support was verified by testing the pure water flux and retention of the PA composite membrane and the structural change of the PA composite membrane before and after use. The results proved the feasibility and remarkable application prospects of hot-pressed wet-laid PET nonwoven support as support for separation membranes.

摘要

在本工作中，采用湿法成网和热压技术制备了聚对苯二甲酸乙二酯（PET）非织造支撑体，并将其用作分离膜的支撑体。研究了PET非织造支撑体的性能，以确定热压参数和PET纤维比例的影响，并通过响应面法进行了优化。结果表明，含有62%低熔点PET（LPET - 180）纤维的PET非织造支撑体在220℃、9MPa压力下热压20s后，获得了令人满意的性能和结构。响应面分析表明，热压温度、时间和纤维比例是影响PET非织造支撑体强度和透气率的最重要因素。热压后，PET非织造支撑体呈现出相互连通的结构、小孔径、低孔隙率和高强度。然后采用相转化技术在PET非织造支撑体上制备聚砜（PSF）层，并通过界面聚合在PSF层上制备超薄聚酰胺（PA）活性层。通过测试PA复合膜的纯水通量、截留率以及使用前后PA复合膜的结构变化，验证了PET非织造支撑体的实用性。结果证明了热压湿法成网PET非织造支撑体作为分离膜支撑体的可行性和显著的应用前景。
