Investigation of miscibility, acoustical parameters and molecular interactions in PVA-PVP polymer blends through viscosity, ultrasonic velocity, DFT, and molecular docking approaches
{{output}}
Context: Water-soluble polyvinyl alcohol (PVA) and polyvinylpyrrolidone (PVP) blends are extensively used in pharmaceutical, paper, and food packaging industries. Miscibility of PVA/PVP blends was first indicated by positive valu... ...
