The influence of graphene addition on the properties of composite membranes RG / PAN and their potential application
AI summary Read the abstract
Researchers added graphene to polyacrylonitrile (PAN) polymer membranes to improve their performance in water filtration applications, finding that graphene enhanced the membranes' mechanical and chemical properties. Advanced membrane filtration is relevant to microplastic removal as these membranes can capture plastic particles from water and wastewater.
PAN is an inexpensive and popular engineering polymer, which is widely used in membrane techniques: ultrafiltration (UF), nanofiltration (NF), reverse osmosis (RO) and pervaporation (PV). It is characterized by good thermal stability, high thermal conductivity, chemical resistance, solubility in many classic solvents, resistance to UV radiation and good mechanical properties. It can be easily modified both chemically and physically. The paper describes the method of obtaining composite membranes by the phase inversion method of homogeneous dispersion of graphene (RG) in a solution of polyacrylonitrile (PAN) dissolved in N, N-dimethylformamide (DMF). The influence of RG concentration on physicochemical properties, transport and separation properties (removing microplastic), and resistance to fouling of composite was investigated.

Synergistic role and performance of graphene oxide–polyvinyl alcohol porous composite membranes for microplastic removal from synthetic wastewater
AI summary Read the abstract
Scientists created a new filter membrane using graphene oxide and a common plastic-safe polymer, designed to trap microplastics from water. In tests, it removed over 90% of one common plastic type (HDPE, found in bottles and containers) and up to 78% of another (polystyrene, used in packaging and foam), and it could be reused multiple times while still working fairly well. This matters because microplastics are increasingly found in our drinking water and bodies, and better filtration technology like this could eventually help reduce our exposure to these pollutants — though the filter still needs improvement before it's ready for widespread use.
