Laser Nanosecond Technique, FTIR and AFM Application to Find Physical Properties of PVA Doped with Dye

The polyvinyl alcohol (PVA) used in this project is made using a casting procedure and doped with various amounts of methyl blue (MB). Infrared spectroscopy using Fourier transforms reveals that the peaks change in wave number and intensity. The measured

Assessment of Surface Modification by Laser Studies of Polymer Material before and after MB Doping

The surface temperature of PVA was calculated before and after laser radiation using optical properties (absorption, transmission, reflection spectra, optical absorption coefficient) and thermal properties (weight after doping, density, and thermal diffusivity). The surface temperature decreased after adding low doping
