Studies on Boron Containing Poly(urethane fattyamide)

Abstract

AbstractSummary: 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.
