Bio-degradable vegetable oil based hyperbranched poly(ester amide) as an advanced surface coating material

Biodegradable polymers from monomers based on vegetable oils

“…The ester bonds could be degraded in the presence of lipase. The obtained adhesion strength, abrasion resistance, scratch hardness, gloss, impact strength and mechanical properties suggest applications in polymeric surface coatings [95,96].…”

“…In addition, the incorporation of aliphatic and aromatic species in polymer backbones improved significantly the biodegradability and biocompatibility, which are important parameters in biomedical and environmental applications [92][93][94]. Linseed [92], pongamia glabra [93], Nahar [94] and castor oils [95,96] In one study, biodegradable hyperbranched polyesteramides were prepared with maleic anhydride, phthalic anhydride and isophthalic acid from N,N-bis(2--hydroxyethyl) ricinoleic fatty amide. The weight average molecular weight of synthesized oligomers was found to be 2300 g mol −1 with dispersity of 1.40.…”

“…Because of the presence of numerous ester linkages in polymer backbones, the thermoset could be biodegraded using P. aeruginosa bacteria. The summarized the fatty acid based thermoset could be potentially used as biodegradable thin film material [95,96].…”

Design novel polyhydroxyl fatty amide based onBalanites roxburgiioil and its application for coating

“…The initial degradation ascribed to the presence of aliphatic segments and final degradation associated with the decomposition of thermally stable amide linkages in the polymeric backbone. [38] The disruption of urethane bonds which causes decomposition of hard segments corresponds to the temperature range 280-320°C. [39] The thermal stability of BUHDI-based polymer is higher than IPDI-and HDI-based polymer due to the higher cross-linking of three NCO group of BUHDI with polyol than IPDI and HDI.…”

“…used for the synthesis of poly(urethanamide), poly(esteramide), and poly(ether amide) for coating applications. [23][24][25][26][27][28] Vegetable oil-dependent industries rely mostly on oils such as linseed oil and soybean oil which are very expensive. In India, a wide variety of wildly grown plants and herbs are available.…”
