Abstract

Castor seed oil (Ricinus communis) is a prominent feed stock towards the generation of renewable materials for industrial production. The reach presence of ricinoleic fatty acid at 87.5% provides pendant hydroxyl functional groups, which is an essential site for chemical formulations. This paper presents the synthesis, characterization, and evaluations on antibacterial and anticorrosive activities of synthesized hybrid composites from Ricinus communis seed oil. N,N'-bis(2-hydroxy ethyl)-12-hydroxy Ricinus communis oil fatty amide (HERCA) was synthesized via aminolysis polyol formation route. Upon reacting HERCA with succinic acid at a high temperature of about 145 ºC, a polyesteramide (RCPEA) was formed. This ester product undergoes urethanation and subsequently interfaced with modified hybrid material. The synthesized composites were characterized using spectroscopic methods such as FTIR, 1H-NMR, and 13C-NMR. Selected physicochemical parameters were also carried out on the products. Coating performance on cured resins was examined.
