STUDIES ON THE ANTIBACTERIAL AND ANTICORROSIVEudPROPERTIES OF SYNTHESIZED HYBRID POLYURETHANEudCOMPOSITES FROM CASTOR SEED OIL

摘要

Castor seed oil (Ricinus communis) is a prominent feed stock towards the generation of renewable materials forudindustrial production. The reach presence of ricinoleic fatty acid at 87.5% provides pendant hydroxyl functionaludgroups, which is an essential site for chemical formulations. This paper presents the synthesis, characterization, andudevaluations on antibacterial and anticorrosive activities of synthesized hybrid composites from Ricinus communisudseed oil. N,N'-bis(2-hydroxy ethyl)-12-hydroxy Ricinus communis oil fatty amide (HERCA) was synthesized viaudaminolysis polyol formation route. Upon reacting HERCA with succinic acid at a high temperature of about 145 ºC,uda polyesteramide (RCPEA) was formed. This ester product undergoes urethanation and subsequently interfaced withudmodified hybrid material. The synthesized composites were characterized using spectroscopic methods such as FTIR,ud1H-NMR, and 13C-NMR. Selected physicochemical parameters were also carried out on the products. Coatingudperformance on cured resins was examined.
