Abstract: Abstarct To improve mechanical strength, polyvinyl alcohol hydrogels were often prepared through freeze-thaw method. However, they usually exhibited micropores limiting their applications. Hence, macroporous polyvinyl alcohol-carboxymethyl cellulose-polyethylene glycol (PVA-CMC-PEG) hydrogels were prepared through phase separation.… read more here.
