What is the role of Polyacrylonitrile (PAN) in the membrane?

Label:chem

Topic
Polyacrylonitrile (PAN) serves as the commercial ultrafiltration membrane substrate onto which ferrocenylmethyl acrylate (FcMA) and methoxy-polyethylene glycol acrylate (PEG 480) were grafted. FTIR analysis confirmed that the chemical structure of the PAN substrate remained intact during the modification process.
Answer
Polyacrylonitrile (PAN) functions as the base ultrafiltration membrane substrate, providing the structural foundation for the grafted catalytic and hydrophilic layers.
