Supramolecular polymers and their application as coating materials

Supramolecular polymers which are formed via non-covalent bonding possess many unique properties.Up to date,three main categories of non-covalent bonding,including coordination,π-stacking and hydrogen bonding,have been used in assembling such polymers.It was found that hyperbranched polymers bearing ureidopyrimidone(Upy) units display good coating performances due to the formation of self-complementary quadruple hydrogen bonding of Upy units.Their melt viscosities are decreased sharply with increasing temperature,which makes the polymers suitable for use as novel hot-melting coating materials.
