Graft polymerization of lauryl acrylate on the surface of polyethylene terephthalate track-etched membranes

Abstract

The attention of many experts in the world is focused on the creation of surface modified materials [1-3]. It was found that chemical modification can be used to change the chemical properties of the surface, primarily its hydrophilicity and hydrophobicity. Physicochemical and chemical interactions of materials are carried out through the surface, and the nature of the surface layer is often crucial in processes such as catalysis, adsorption, filtration, etc. This can explain the great interest in surface modification of various materials. In this case, chemical bonding of various compounds on a solid carrier occurs, leading to the production of new materials with a number of properties that neither the carrier nor the grafted compound possessed. Track membranes, including those modified by various methods, are currently used in the processes of membrane catalysis, hydrogen energy, nanofiltration and separation of liquids, natural water purification and environmental pollution analysis, purification of liquids and gases, water purification from heavy metals, etc. [6] Sensors capable of detecting lower and lower concentrations heavy metal ions with greater accuracy and speed are necessary for effective water quality control and prevention of poisoning
