Temperature-sensitive Properties of PNIPAm/PVA Hydrogel Fibers Used for Artificial Muscles

Poly(N-isopropylacrylamide) (PNIPAm) was in situ polymerized in polyvinyl alcohol (PVA) aqueous solution with N isopropylacrylamide (NIPAm) as monomer, ammonium persulfate (APS) as initiator, and the transparent solution of PNIPAm/PVA blending was obtained. PNIPAm/PVA fiber was successfully prepared from the PNIPAm/PVA blending solution via wet spinning process with the saturated ammonium per sulfate aqueous solution as coagulation bath and the glutaraldehyde as crosslinker. The swelling performance and temperature-sensitive behaviors of the PNIPAm/PVA hydrogel fiber were studied and implications for the design of temperature-responsive actuators (artificial muscles) from these materials were discussed.
