Abstract

Abstract: 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, 1 H‐NMR, 13 C‐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°C [higher than tetraniline] and σ = 8.9 × 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.
