Cu Crystal Growth on a Chelating Fiber with Different Amine Chain Lengths

Summary: Poly(acryloamidino ethyleneamine) (PAEA) and poly(acryloamidino diethylene diamine) (PADD) have been synthesized for the observation of Cu^II complex and Cu(OH)₂ crystal‐growth on the surface of different numbers of amino groups immobilized on polyacrylonitrile (PAN) fibers. The shape of Cu^II crystal growth depends on the amine chain length of the chelating fiber; Cu(OH)₂ crystals grow on the surface of the chelating fiber after Cu^II adsorption.
