Abstract

Currently, the pre-treatment for membrane filtration systems is receiving more attention that can be remove large particles and debris or enhance permeation flux. In this study, commercial nylon 6 fabric is modified via hydrolysis amidation reaction in alkaline media with NaOH and Dimethylene diamine. The increase of hydrophilicity amino groups on the surface of treated fabric which increases the hydrophilicity of the fabric. This opens up new possibilities for the treatment process in commercial membrane filtration systems. Besides, amino enriched nylon 6 fabric can capture carboxylic functionalized carbon-based nanomaterials forwards to the synthesis of thin film nanocomposite membranes based on carboxylated multi-walled carbon nanotubes.
