What is the role of Methoxy-polyethylene glycol acrylate (PEG 480) in the modified membrane?

Label:chem

Topic
PEG 480 was grafted onto the PAN membrane along with FcMA to enhance its hydrophilicity. Grafting PEG significantly decreased the water contact angle of the membrane, improving its wettability. In membrane M2, PEG 480 was incorporated to balance the hydrophobicity introduced by ferrocene groups, leading to improved hydrophilicity and pure water flux compared to membranes modified solely with FcMA.
Answer
Methoxy-polyethylene glycol acrylate (PEG 480) is incorporated into the membrane to improve its hydrophilicity and mitigate the hydrophobic effects of ferrocene, which enhances water permeability and overall membrane performance.
