Abstract:Poly(N‐isopropyl acrylamide) (PNIPAm)‐based smart hydrogels are widely employed in emerging applications such as drug delivery and tissue engineering, because their lower critical solution temperature (LCST) is close to physiological conditions. However, the dense chain collapse during the thermo‐responsive phase transition restricts water diffusion, resulting in limited volumetric change. Here, a pure PNIPAm hydrogel that achieves a large‐scale volume transition by incorporating PNIPAm microgels, is presented… Show more
