Abstract

The effects of tin disulfide (SnS2) addition on the mechanical, thermal, and optical characteristics of polyvinyl alcohol (PVA) were determined in this study. The solvent-casting approach was used to create composite films with varying SnS2 weight ratios. Mechanical testing revealed that the addition of SnS2 raised the tensile strength (TS) of the virgin PVA from 32.10 MPa to 47.50 MPa, while the elongation at break (EB) increased from 78.40% to 108.80%. Optical investigations revealed that PVA and SnS2 had intermolecular interactions. Furthermore, the contribution of SnS2 resulted in a drop in energy bandwidth from 5.310 eV to 4.821 eV. Thermal investigations revealed that PVA/SnS2 had greater stability than the virgin polymer. Given the data obtained, it was obtained that the addition of SnS2 simultaneously enhanced the mechanical, thermal, and optical properties of PVA.
