Abstract EN
The aim of this present work is to investigate the effect of plasticizers like Sorbitol on microstructural and mechanical properties of hydroxypropyl methylcellulose (HPMC) and Polyvinylpyrrolidone (PVP) blend films.
The pure blend and plasticized blend films were prepared by solution casting method and investigated using wide angle X-ray scattering (WAXS) method.
WAXS analysis confirms that the plasticizers can enter into macromolecular blend structure and destroy the crystallinity of the films.
FTIR spectra show that there are a shift and decrease in the intensity of the peaks confirming the interaction of plasticizer with the blend.
Mechanical properties like tensile strength and Young’s Modulus decrease up to 0.6% of Sorbitol content in the films.
Percentage of elongation at break increases suggesting that the plasticized films are more flexible than pure blend films.
These films are suitable to be used as environmental friendly and biodegradable packaging films.
