Polymer-Based Muscle Expansion and Contraction

Weight lifting: A polymer‐based device capable of lifting many times its own mass was fabricated by drying a solution of the polycation poly(diallyldimethyl ammonium chloride) (pDADMAC) on a surface coated with charged poly(N‐isopropylacrylamide)‐based microgels. Upon drying of the pDADMAC solution...

Description
Summary:Weight lifting: A polymer‐based device capable of lifting many times its own mass was fabricated by drying a solution of the polycation poly(diallyldimethyl ammonium chloride) (pDADMAC) on a surface coated with charged poly(N‐isopropylacrylamide)‐based microgels. Upon drying of the pDADMAC solution on the microgel‐modified surface, it bends. Flexible surfaces then curl up into scroll‐like structures, which can be opened up at high humidity.
