Abstract
- Vegetable oil-based composites have been proposed as interesting bio-based materials in the recent past. The carbon&ndash<br />carbon double bonds in unsaturated vegetable oils are ideal reactive sites for free radical polymerization. Without the presence of a reinforcement, typical vegetable oil-based polymers cannot achieve competitive thermo-mechanical properties. Compatibilizers have been utilized to enhance the adhesion between resin and reinforcement. This work discusses the antagonist implications of polarity and crosslink density of an unprecedented polar &alpha<br />eleostearic acid-based resin reinforced with &alpha<br />cellulose, eliminating the need of a compatibilizer. It is shown that the polar regions of &alpha<br />eleostearic acid can interact directly with the polar reinforcement. The successful isolation of &alpha<br />eleostearic acid from tung oil was verified via GC-MS, 1H NMR, Raman, and FT-IR spectroscopies. The optimal cure schedule for the resin was determined by DSC and DEA. The composites&rsquo<br />thermo-mechanical properties were assessed by TGA, DSC, and DMA.
