The effect of nanoclay on interfacial adhesion in PLA/PBAT/Nanoclaynanocomposites

Biodegradable nanocomposite of poly(butylene adipate-co-butylene terephthalate)(PBAT)/poly(lactic acid) (PLA) incorporated with nanoclay as a compatibilizer were developed bymelt processing. The effect of weight percentages of nanoclay on the mechanical properties andmorphology was investigated. Elongation, yield stress and modulus of elasticity were measured usingtensile test. FESEM was also employed to investigate the changes in morphology and the dispersionof nanoparticles within the polymer matrix. Increasing the amount of PBAT enhances the toughnessand elongation of the nanocomposite and decreases the modulus. Additionally, the presence ofnanoclay in the sample improves the distribution of PBAT, making the components of the compositemore compatible and enhancing the mechanical properties
