“…Triglyceride oils have been extensively used for various applications such as coatings, inks, agrochemicals etc. [32]. These oil-based polymeric materials, however, do not show properties of rigidity and strength required for structural applications by themselves.…”

Abstract:Green nanocomposites based on renewable plant oils and polyhedral oligomeric silsesquioxanes (POSS) have been developed. An acid-catalyzed curing of epoxidized plant oils with oxirane-containing POSS derivatives produced transparent nanocomposite coatings with high gloss surface, in which the organic and inorganic components were linked via covalent bonds. The hardness and mechanical strength were improved by the incorporation of the POSS unit into the organic polymer matrix. Nanostructural analyses of the nanocomposites showed the formation of homogeneous structures at the micrometer scale. On the other hand, such improvements of the coating and mechanical properties were not observed in the composite without covalent bonds between the plant oil-based polymer and POSS unit. The study demonstrates the correlation between the nanostructure of composites and macroscopic properties.

“…Among the renewable raw materials for polymer production, some of the plant oils are the most promising candidates due to their characteristic molecular structure, non-volatility and biodegradability [4,5]. Edible plant oils are essentially used as a food source; however, the supply-demand balance for this market would break down if these oils were used for large-scale polymer production.…”

Abstract:Methyl epoxyricinoleate was prepared in high yield by the lipase-catalyzed epoxidation of methyl ricinoleate with H 2 O 2 . A high molecular weight polyepoxyricinoleate (PER) with a maximum weight average molecular weight (M w ) of 272,000 was enzymatically prepared by the polycondensation of methyl epoxyricinoleate using immobilized lipase from Burkholderia cepacia (lipase PS-IM) in bulk at 80 C for 5 d. PER showed good low temperature fluidability. PER was readily cured by maleic anhydride (MA) at 80 C to produce a chloroform-insoluble PER-MA film. Both the glass transition temperature and Young's modulus increased with increasing MA content and PER M w . In contrast, the elongation at break decreased with increasing MA content and PER M w . Methyl epoxyricinoleate, PER and PER-MA showed biodegradability by activated sludge, and that of the PER-MA film decreased with increasing MA content.

“…However, in spite of such versatility, some of the disadvantages like low toughness, high brittleness and non-biodegradability restricting their utilizations in many advanced applications. Also, the global concern regarding the degradability of polymeric materials in environment compelled the scientists to explore the renewable resources in the production of useful materials (Velayutham et al, 2012;Yang et al, 2011;Biermann et al, 2000;Mungroo et al, 2008;Singh, et al, 2012). Therefore, to overcome such limitations, bio based epoxy resins were produced from vegetable oils.…”

Bio-based hyperbranched and linear epoxy resins were synthesized from monoglyceride of Ricinus communis oil. The nanocomposites of these hyperbranched and linear epoxies with 1, 2 and 3 wt% of OMMT were also fabricated. The structures of the resins and their nanocomposites were analyzed by FTIR, NMR, XRD, SEM and TEM. The studies of performance characteristics of poly(amido amine) cured thermosetting nanocomposites showed significant improvements in tensile strength from 5.8 to 11.9 MPa, impact from 80 to >100 cm, scratch resistance from 4 to 9 kg, thermal stability from 213 to 316°C and chemical resistance over their pristine systems. Further, hyperbranched nanocomposites and bio-based epoxy thermosets exhibited better performance than the linear and petroleum based ones. The overall results, therefore, demonstrated hyperbranched epoxy/clay nanocomposites as potential materials for advanced applications.
