Abstract

A hybrid double-network poly(N-isopropylacrylamide) (PNIPAm-co-PAA)/nanocellulose hydrogel was fabricated by inverted stereolithography (inverted-SLA) 3D printing to establish a new materials platform that exhibits attractive tunable properties including stretchability, thermo-responsivity, optical switching, and bio-adhesivity. It was found that PNIPAm-co-PAA/CNF hydrogels are stretchable and exhibit switchable bio-adhesivity in response to external modulation of the lower critical solution temperature (LCST). Further, changes in the transparency of the PNIPAm-co-PAA/nanocellulose as a function of elongation and LCST modulation were observed. These latter exciting phenomena in the as-printed PNIPAm-co-PAA/nanocellulose hydrogels can be attributed to an interpenetrating polymer network (IPN) of crosslinked PNIPAm and nanocellulose. The prepared PNIPAm-co-PAA/nanocellulose hydrogels can be used as durable temperature-sensitive sensors and functional biomedical devices.<br/>
