Designing multifunctional cotton fabrics based on dipentaerythritol pentaacrylate-branched poly(ethyleneimine) (5Acl-BPEI) reactive coating

The application of functional textiles in our daily life is expanding increasingly. However, manufacturing, designing, and developing mild but efficient functional textiles remains a challenge. In this work, a straightforward method to construct functional cotton fabrics (CF) with superhydrophobicity and antibacterial activity using dipentaerythritol pentaacrylate-branched poly(ethyleneimine) (5Acl-BPEI) reactive coating as the secondary reactions layer and subsequently treating with bis(3-aminopropyl)-terminated poly(dimethylsiloxane) (PDMS-NH2) and 1-(12-(mercaptododecyl)-3-methylimidazolium bromide (MDMIBr). The obtained CF@5Acl-BPEI@PDMS-NH2 showed integrated performances with hydrophobic behavior (water contact angle of 151.7 ± 0.8° and sliding angle of 8.8 ± 0.9°), self-cleaning, excellent efficiency in oil–water separation (above 99.4
