Abstract
ABSTRACT Reverse osmosis (RO) membranes have been widely used in the field of membrane separation. However, most of the commercial RO membranes are fabricated based on a polysulphones- or polyethersulfone-modified polyethylene glycol terephthalate (PET) support, which are thick and exhibit poor solvent resistance. In this study, polyethylene (PE) battery membranes without any hydrophilic modification were directly used to prepare PE-RO membranes. The structures of the products were confirmed via attenuated total reflection Fourier transform infrared spectroscopy, X-ray photoelectron spectroscopy, and scanning electron microscopy. The resulting RO membrane prepared with 0.05 wt.% of trimesoyl chloride and 2 wt.% of m-phenylenediamine exhibited a water flux of 12.61 L m−2 h−1 with a desalination (NaCl) rate of 98.6%. The thickness of the PE-RO membrane is 80% of the thickness of the traditional RO membranes and hence has a wider application as a separation membrane.
反渗透(RO)膜在膜分离领域得到了广泛的应用。然而，大多数商用反渗透膜是基于聚砜或聚醚砜改性聚乙二醇对苯二甲酸乙二醇酯(PET)载体制成的，这种载体很厚，耐溶剂性很差。本研究采用未经亲水性改性的聚乙烯(PE)电池膜直接制备PE- ro膜。通过衰减全反射傅里叶变换红外光谱、x射线光电子能谱和扫描电镜对产物的结构进行了确证。所得反渗透膜的水通量为12.61 L m−2 h−1，脱盐率(NaCl)为98.6%，三甲基氯含量为0.05%，间苯二胺含量为2%。PE-RO膜的厚度是传统反渗透膜厚度的80%，因此作为分离膜有更广泛的应用。
期刊介绍：
Materials Research Innovations covers all areas of materials research with a particular interest in synthesis, processing, and properties from the nanoscale to the microscale to the bulk. Coverage includes all classes of material – ceramics, metals, and polymers; semiconductors and other functional materials; organic and inorganic materials – alone or in combination as composites. Innovation in composition and processing to impart special properties to bulk materials and coatings, and for innovative applications in technology, represents a strong focus. The journal attempts to balance enduring themes of science and engineering with the innovation provided by such areas of research activity.
