    Thin-film coatings based on PMOX and its copolymers with negative, neutral, and positive ζ-potential were investigated to tackle the problem of marine and bacterial fouling prevention. The coatings were stable in sea water for at least 1 month without significant reduction in the film thickness. Performance tests showed that PMOX coatings effectively reduced bacterial Staphylococcus aureus and Escherichia coli adhesion and possessed marine antifouling activity against barnacle cyprids Amphibalanus amphitrite and algae Amphora coffeaeformis.

    Synthesis of hydroxyl-polyurethanes through ring-opening reaction of cyclic carbonate with amines is a potentially useful green process without toxic isocyanates. In this study, a linear homo-polymer, poly(isopropenylphenoxy propylene carbonate), [poly (IPPC)] is prepared, possessing multi-cyclic carbonates on the side-chain through cationic polymerization of IPPC. Thus, curing of the poly(IPPC) with diamines readily resulted in the formation of hydroxyl-polyurethanes on the side-chain which were characterized by the initial soluble phase but then turned into the final insoluble crosslinked films upon solvent removal.

  3. N-bromo-hydantoin grafted polystyrene beads: Synthesis and nano-micro beads characteristics for achieving controlled release of active oxidative bromine and extended microbial inactivation efficiency

    Chemically or kinetically release modified N-halamine hydantoins conjugated polystyrenes beads were studied. Beside chemical modifications, bead's nano-micro characteristics were found critical for oxidative halogen release control: rate stabilization and modulation, extension and also influences antimicrobial activity. Distinct controlled releasing profiles were found and extended strong antimicrobial activity for hundreds of liters. These parameters are important to explore, since the rate of halogen release influences antimicrobial activity and subsequently the material usage for different applications.

    A small band gap conjugated polymer with ternary acceptors of diketopyrrolopyrrole, benzothiadiazole, and naphthalenediimde is presented. Nanowires of this polymer were fabricated to show ambipolar field-effect transistors with hole and electron mobilities of 1.61 and 0.98 cm2 V−1 s−1.
