Poly(vinyl alcohol) (PVA) is an excellent membrane-forming polymer and can be modified with potato starch and methyl acrylate monomers to obtain copolymers with improved physical and chemical properties. The study presents the synthesis of poly(vinyl alcohol)-g-starch-poly(methyl acrylate) PVA-g-St-g-PMA copolymers using microwave irradiation technique and potassium persulfate initiator. Solution casting and solvent evaporation methods were adopted for the fabrication of polyvinyl alcohol-g-starch-acrylamide composite membranes. The synthesized graft copolymer was characterized by Fourier transform infrared spectroscopy, scanning electron microscopy, and thermal analysis. The modified nanocomposite membranes were showed very promising results with the parameters permeability and selectivity. The nanocomposite membranes exhibited the advantages of easy handling and reuse.

Numerous corporations have overlooked environmental regulations concerning wastewater treatment, leading to a worldwide issue regarding hazardous pollutant discharge, particularly dyes and heavy metal ions, into river sources. Various industries, with water, energy, and biological sectors, actively employ membranes. Membranes capable of showing flux, metal and dye sorption, and catalysis have been developed and are extensively used by functionalizing the pores of ultrafiltration, microfiltration, and nanofiltration membranes with responsive properties.

Membrane desalination is an economical and energy-efficient method to meet the current worldwide water scarcity. However, state-of-the-art reverse osmosis membranes are gradually being replaced by novel membrane materials as a result of ongoing technological advancements. These novel materials possess intrinsic pore structures or can be assembled to form lamellar membrane channels for selective transport of water or solutes (e.

Nanocomposite films made from graphene oxide (GO) and MXene have a dense layered structure due to nanosheet self-stacking, limiting their dye adsorption performance. In this study, acid-base neutralization reactions are used to induce MXene/reduced graphene oxide (RGO) films bulging, which opens the stacked layer structure within the membrane and enhances MB adsorption performance. The effects of the pH, temperature, contact time, and initial concentration of MB on the adsorption performance are further investigated.
