Abstract
Ten ZnO–starch composites were synthesized using a simple precipitation methodology The IR spectroscopy and XRD investigations reveal the presence of amorphous starch and crystalline ZnO The obtained composites present a spherical morphology 5–8 spheres being interconnected into aggregates The thermal analysis demonstrates that starch decomposition and ZnO thermally induced nucleation and crystal growth depending on the synthesis parameters such as starch processing dissolution or gelatinization reaction temperature 80 90 and 100 °C reaction time 15 min or 6 h and applied treatments heating or ultrasound irradiationThe paper done within the research program “Biophysical and green chemistry applications” of the “Ilie Murgulescu” Institute of Physical Chemistry of the Romanian Academy was supported by a grant of the Romanian National Authority for Scientific Research CNCSUEFISCDI project number PNIIIDPCE201130473
