Properties of Ternary Blends of Compostable PLA/PBAT/PBS

Compostable plastics such as Poly (lactic acid) (PLA), Poly(butylene succinate) (PBS) and adipate-coterephthalate) (PBAT) have been extensively used in many applications, from commodity to engineering ones. These offer the circularity of carbon cycle. However, each them has advantages disadvantages. The ternary blend these three are therefore very interesting terms phase morphology their physical properties while offering compostable practices. In this work, blends PLA/PBAT/PBS were studied. PLA/PBAT was fixed at 50/50 whereas PBS varied 10 40 % wt. order ensure compatibility, peroxide carbodiimide compounds used. results show an immiscibility blend, with continuous surface PLA PBAT is dispersed phase. it shows better interfacial adhesion when reactive added. mechanical indicated modulus all higher than neat (~52 MPa) (~377 MPa). insignificantly changed increased contents, similar tensile strength results.
