In this work, new materials based on the blends of polyvinyl alcohol (PVA), polyvinyl pyrrolidone (PVP), chitosan (CS), and polydopamine (PDA) have been prepared. Fourier Transform Infrared Spectra have been conducted to verify the presence of individual components in the composite materials. EDX elemental analysis showed a clear view of the element's presence in the composite materials, with the maximum values for carbon and oxygen.

Acne skin care aims to reduce the stratum corneum layer, normalization of sebum secretion, and mitigation of purulent lesions. Antibiotics, such as macrolides, clindamycin, and tetracyclines, are often used in acne treatment. In clinical practice, the resistance of antibiotics has become an increasing issue.

In this work, blend films were prepared by blending 2% chitosan (CS) and 0.5% konjac glucomannan (KGM) solutions. Five ratios of the blend mixture were implemented (95:5, 80:20, 50:50, 20:80, and 5:95), and a pure CS film and a pure KGM film were also obtained.

In this study, the synthesis of poly(AVGVP) [where A-Alanine, V-Valine, G-Glycine, and P-Proline] is executed by the stepwise solution phase method. The interaction between Chitosan and synthetic polypentapeptide in blends was examined in the liquid and solid phases. Viscosity criteria that establish the total miscibility with Chitosan are the Δ[η], the intrinsic viscosity [η], Huggins coefficient [], by Garcia Δ, α by Sun, and μ suggested by Chee, Δ, and β buttressed by Jiang and Han.
