Formation of PVA-PMMA-PAAm blend with various content of dextrin for drug delivery application

In recent years, there has been a surge in interest in developing new polymeric materials with high performance and low cost. With increased environmental awareness, research has focused on eco-friendly materials, with terms like “renewable,” “recyclable,” “sustainable,” and “biodegradable” becoming important features of the materials, Polymer blends can provide products with a wider range of useful qualities than single polymer equivalents. In this study, Polymer blend films were prepared using dextrin at different compositions of (PVA- PMMA-PAAm) by solvent casting method. The prepared blend films were flexible and transparent and characterized using was examined by scanning electron microscopy to examine the surface morphology of the samples that show the good distribution of starch in the blend, while FT-IR was used to identify the active groups, which refer to the interaction among the materials. Also, we have studied the optical properties and recording the absorption spectrum with a visible ultraviolet spectrophotometer. Absorption spectra were recorded in the wavelength range of 200–1100 nm. The absorbance and optical conductivity were increased by dextrin additive, while the transmittance and energy gap decreased. Based on the overall results, the prepared films can be used in drug delivery and optical devices. © 2021
