WebNov 3, 2015 · In this article, we report a novel method for synthesizing temperature-sensitive polymer-modified cellulose nanofibril (CNF) cryogel microspheres. The pristine cryogel microspheres were first prepared using a spray-freeze dry method in the presence of a chemical crosslinker. Afterwards, NIPAm (N-isopropylacrylamide), a temperature … WebThe obtained flexible cryogel displayed a three-dimensional structure composed of thin sheet. The maximal shape recovery of the CNF-supported cryogel from a 50% compression strain was up to 93% of its original thickness. The cryogel contained abundant amino groups and proved to be efficient in removing Cu²⠺ from solution with a maximum ... harvest at ovation taylor morrison
