Abstract

Graphical abstract: Highlights: Utilized renewable, bio-based and bio-degradable materials to synthesize chitosan-based polybenzoxazine. A simple reaction process was carried out by adopting Mannich condensation, where water as an eco-friendly solvent was used. Synthesised compounds that are tested in vitro are also harmless in vivo and may have clinical relevance as alternative method for human pathogenesis. Abstract: Renewable materials are abundantly available in nature and have the capability to degrade within a short period of time. In the present study, a novel class of chitosan-based polybenzoxazine has been synthesized for the first time. Water, an edible solvent was used for the benzoxazine synthesis, adopting moderate reaction temperature. This bio-based benzoxazine monomer was crosslinked by thermal treatment via ring-opening polymerization to form free-standing polymer films [poly(E-Ch)] without the evolution of volatiles. Hydrogen bonding interactions were found to exist between chitosan and polybenzoxazine. This type of interactions significantly enhance the thermal and mechanical properties with T10 of about 260 °C; ε′ of about 3.6 GPa; and Tg of about 135 °C showing unusual levels of synergism. Interestingly, both the bio-films-poly(E-Ch) and CH do not affect the cell growth. In particular, poly(E-Ch) is effective in preventing bio-film associted infections.
