摘要

Today every single step toward green chemistry is a high priority to avoid global warming and environmental contaminations. In this regard, conductive, asymmetric star-shaped, bio-based structures, comprising tetramers of aniline (SSB-TA) was synthesized from bio-sourced resin using microwave irradiation. The hydroxyl-functional SSB-TA was characterized by FT-IR, H-1-NMR, C-13-NMR, and the thermal, mechanical and electrical properties of oligomer and its hybrid with poly (hydroxyethyl methacrylate), (HEMA) were measured by TGA, DMTA and four probe conductometer. Results show that SSB-TA is highly thermal-stable conductive biobased oligomer (T-50 = 452 degrees C higher than tetraniline and sigma = 8.9 x 10(-4) S cm(-1)) and 2.5 SSB-TA is the optimum content to improve thermal properties up to 62 and enhance the level of electrical conductivity of poly (HEMA) 12 times. This functional structure can be considered as a suitable candidate to be employed in tissue engineering and biobased adhesives contributing into the self-assembly process, post treatment reactions as well as additive in not only HEMA but also star-shaped lactic acid-based systems.
