In this work, renewable composites were prepared by the association of a thermosetting resin synthesized via free-radical polymerization, using mixture tung oil, n-butyl methacrylate, and divinylbenzene, with silica-rich fillers, namely an algae biomass high silica content, well-sorted sand. Furthermore, to investigate if interaction between non-polar polar reinforcements could be improved, enhancing materials’ mechanical properties, itaconic anhydride, bio-derived molecule obtained from...
Natural polymers, such as starch, and polymers derived from renewable resources, vegetable oils, have been considered alternatives to petroleum-based plastics during recent decades, due environmental concerns. Indeed, these materials can offer a variety of advantages, low cost, wide availability, carbon neutrality, elevated thermal stability, easily tunable mechanical properties. However, some alone exhibit poor properties, making them not suitable for applications. Hence, the reinforcement...
Unsaturated vegetable oils with conjugated carbon–carbon double bonds, such as tung oil, can undergo free-radical polymerization, originating alternatives to petroleum-based materials. The introduction of fillers oil-based polymer matrices results in composites improved mechanical properties. In this work, thermosets were synthesized by the polymerization a mixture divinylbenzene, and n-butyl methacrylate, reinforced bio-based fillers, namely Miscanthus, Pinus taeda (also known southern...
In this work, bio-based composites were prepared by transesterification of different types lignin with tung oil followed co-polymerization divinylbenzene in the presence pine wood particles. The results obtained reveal that regardless source used, preparation was successful, less than 20 wt % unreacted material recovered after Soxhlet extraction and no residual curing detected via Differential Scanning Calorimetry (DSC). Thermogravimetric Analysis (TGA) showed addition particles to...
