“…Silica nanoparticles have been considered to improve the performance of a coating prepared from castor oil and an isocyanate alkyl triethoxy silane, further hydrolyzed to form an organic-inorganic hybrid coating [119]. Similarly, Sharmin et al prepared a mixture of DGEBA epoxy and castor oil in a ratio of 70/30 by weight, and 10 wt% of prehydrolyzed TEOS [120].…”

Polymeric materials from renewable resources have attracted a lot of attention in recent years. The development and utilization of vegetable oils for polymeric materials are currently in the spotlight of the polymer and chemical industry, as they are the largest renewable platform due to their universal wide availability, ingrained biodegradability, low cost, and excellent environmental aspects (i.e., low ecotoxicity and low toxicity toward humans). These excellent natural characteristics are now being taken advantage of in research and development, with vegetable oil derived polymers/polymeric materials/composites being used in numerous applications including paints and coatings, adhesives, and nanocomposites. The aim of this review paper is to give a fundamental description of the various vegetable oil applications in polymer materials and its recent developments. Particular emphasis will be placed on study and main application of triglyceride based additive for polymer and to give the reader an insight into the main developments is discussed.

“…Epoxidized oils can also be cured directly using a cationic photoinitiator . A less common approach is to synthesize alkoxysilane derivatives of oils and to incorporate them into UV cured coatings via the sol–gel route . Besides, oils were acrylated via Diels Alder reaction, thiol‐ene reaction, direct esterification from the hydroxyl groups (castor oil), bromoacrylation (by using N‐bromosuccinimide), and direct urethanation of the hydroxyl groups (castor oil) to be used in photocurable coatings.…”

Direct preparation of coatings from neat vegetable oils without any pretreatment or modification is an elegant way of demonstrating the potential of renewable sources and it is also in line with the principles of Green Chemistry.In this work, photocured coatings were prepared from tung oil (TO), hazelnut oil (HN), and isosorbide. First, a dithiol derivative of isosorbide (ISTMP) was synthesized and then mixed with TO, HN, and a cationic photoinitiator. For comparison, formulations were also prepared by using two different commercial thiol compounds. Coating formulations were applied onto glass substrates and cured under UV light where oxidative polymerization and photoinitiated thiol-ene addition reactions took place concomitantly. Double bond conversion percentages, thermal degradation properties, water contact angles, and surface hardness of the coatings were determined. Furthermore, a model reaction between ISTMP and oleic acid was performed to prove that ISTMP reacts with the fatty acid. ISTMP containing formulation displayed a fast initial double bond conversion and its water contact angle value was found as 88 ± 3 . Rigid and thermally stable isosorbide ring improved both the thermal properties and the surface hardness of the coatings.

Non-biodegradable polymers are causing severe damage to the environment. To counter this, need of biodegradable polymers is gaining a rapid growth in numbers as well in their applications and quantities used. In addition, due to the oil crises worldwide, focuses from synthesizing polymers from petroleum has shifted to the synthesis of polymers from renewable resources such as vegetable oils. The advantage of vegetable oils is they are easily available, have multiple functional groups attached like the double bonds, hydroxyl groups and other functional groups, which provides ease of reactions and modification like epoxidation etc. The use of vegetable oils in the polymer renders biodegradability to the polymer. Different researchers have used different vegetables oils like castor oil, linseed oil, soybean oil, sunflower oil and canola oils for synthesis of polymers and utilized them in diverse fields like biomedical, coatings, adhesives, IPN's and as structural materials. This review discusses the synthesis, characterization, degradation and applications of polymers obtained from natural oils such as castor oil, soybean oil, linseed oil and some other oils.
