“…A special use for biopolymers is when applying them as biomaterials. For this, materials are developed in order to be used in biological systems, such as in devices for controlled release of drugs, dressings, artificial skins and support for cell growth (TROVATTI et al, 2016). In this context, the present study sought to produce and characterize a biopolymer, poly-(sorbitol co-citrate adipate) using raw materials, sorbitol, citric acid and adipic acid (Figure 1), from renewable and low sources cost in substitution of petroleum-derived polymers, aiming at applications such as biomaterial (DE FARIAS et al, 2016;.…”
