Abstract EN
The objective of the present work was to study the incorporation of starch nanoparticles (SNP) produced by ultrasound in blends of poly(butylene adipate-co-terephthalate) (PBAT) and thermoplastic starch (TPS).
The films were produced by extrusion using varying percentages of SNP (1, 2, 3, 4, and 5% w/w).
The SNP were prepared in water without the addition of any chemical reagent.
The results revealed that ultrasound treatment results in the formation of SNP less than 100 nm in size and of an amorphous character and lower thermal stability and low gelatinization temperature when compared with cassava starch.
Scanning electron microscopy (SEM) showed that films presented some starch granules.
The relative crystallinity (RC) of films decreases with increasing concentration of SNP.
The addition of SNP slightly affected the thermal degradation of the films.
The DSC results showed that the addition did not modify the interaction between the different components of the films.
Mechanical tests revealed an increase in Young’s modulus (36%) and elongation-at-break (35%) with the incorporation of 1% SNP and this concentration reduced the water vapor permeability (53%) and significantly decreased the water absorption of the films, demonstrating that low concentrations of SNP can be used as reinforcement in a polymeric matrix.
