Abstract
An attempt has been made to synthesize boron containing poly (urethane-fattyamide) [B-PUPGFA] through the incorporation of boron in the backbone of non drying oil such as Pongamia glabra oil derived poly (urethane-fattyamide). The synthesis route involves 50% reduction in the use of harmful volatile organic contents [VOCs] and was carried out in situ by condensation reaction between N, N'-bis (2-hydroxyethyl) Pongamia glabra fattyamide and boric acid without solvent followed by the addition polymerization with toluene diisocyanate in minimum solvent. Spectral (FTIR, 1H-NMR and 13C-NMR), physico-chemical, physico-mechanical and chemical resistance of B-PUPGFA was carried out by standard laboratory methods. The antibacterial performance of B-PUPGFA was done by agar diffusion method against E. coli and S. aureus. The aforementioned performance of B-PUPGFA was compared with Pongamia glabra oil based virgin poly (urethane-fattyamide) [PUPGFA]. It is observed that the incorporation of boron has a significant influence on the overall performance of B-PUPGFA film, which shows antibacterial activity against E. coli and S. aureus. Therefore, B-PUPGFA serves as novel and promising biomaterial candidate for use as anticorrosive and antibacterial coating material.
