Abstract
Environmental issues and reduction of fossil resources led to the partial or total substitution of petroleum based materials with natural raw renewable ones. The continuous decrease in world oil reserves and unpredictable price fluctuations compelled both academia and the industry to invest massively in the production of new materials. One expanding domain is the obtaining of engineering materials from raw renewable natural resources as sustainable eco–friendly polymers for different applications. This is the first study on the obtaining, thermal, morphological, dielectric and wettability characterization of a composite from thermally cured solvent–free bio–based epoxidized and acrylated soybean oil containing low quantities of reactive diluent and TiO2 microparticles as filler. The microcomposite also possessed reduced initial matrix formulation viscosity and without the toxic curing agents. The material was characterized by Fourier–transform infrared spectroscopy, differential scanning calorimetry, thermogravimetry, scanning electron microscopy, broadband dielectric spectrometry and contact angle measurements. Here we demonstrate that the composite exhibits superior thermal stability, glass transition temperature, dielectric constant and hydrophobicity to the pristine matrix. All investigations recommend the microcomposite for optoelectronic devices and as layer in thin–film transistors. This study brings new contributions to green chemistry and sustainable materials.
