Surface modification of microporous polypropylene membrane by UV-initiated grafting with poly(ethylene glycol) diacrylate

Surface modification of microporous polypropylene membrane by UV-initiated grafting with... Abstract Poly(ethylene glycol) diacrylate (PEGDA) was grafted, through UV-initiated grafting, onto a microporous polypropylene (PP) membrane in order to develop a moisture-sensitive porous structure. Based on the concentration of the PEGDA grafting solution, as well as other variables, the pores of the membrane were filled to varying degrees with cross-linked PEGDA hydrogel, decreasing the pore sizes. This decrease in pore size was highly dependent on the grafting degree (weight add-on of the grafted polymer) that was dependent upon grafting conditions. Grafting with PEGDA resulted in a microporous polypropylene membrane with increased hydrophilicity and moisture-responsive pores. The functional membrane can be used in biological protective materials to limit the transport of liquid-borne pathogens while maintaining moisture transport properties. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Fibers and Polymers Springer Journals

Abstract

Abstract Poly(ethylene glycol) diacrylate (PEGDA) was grafted, through UV-initiated grafting, onto a microporous polypropylene (PP) membrane in order to develop a moisture-sensitive porous structure. Based on the concentration of the PEGDA grafting solution, as well as other variables, the pores of the membrane were filled to varying degrees with cross-linked PEGDA hydrogel, decreasing the pore sizes. This decrease in pore size was highly dependent on the grafting degree (weight add-on of the grafted polymer) that was dependent upon grafting conditions. Grafting with PEGDA resulted in a microporous polypropylene membrane with increased hydrophilicity and moisture-responsive pores. The functional membrane can be used in biological protective materials to limit the transport of liquid-borne pathogens while maintaining moisture transport properties.
