Thin films of polymer blends deposited by matrix-assisted pulsed laser evaporation: Effects of blending ratios

▶ We obtain thin films of PEG:PLGA blends with different blending ratios using MAPLE. ▶ We study the influence of the blending ratios on the characteristics of the films. ▶ The films are smoother for blends with higher content of PEG. ▶ The intensity ratios in the FTIR spectra are consistent with the blending ratios. ▶ The films have lower refractive indices for blends with higher content of PEG.
