Abstract

Thermal properties such as thermal diffusivity and thermal conductivity are measured by photoacoustics at room temperature for various particle sizes, thicknesses and the percentage of mixing of poly (vinyl alcohol) (PVA) in Poly (vinylidene fluoride) (PVDF)/PVA blends. The results are compared with other experimental reports, which is by laser flash technique for various temperatures. The agreement is very good at room temperature; in our study, it is 0.20 Wm−1 K−1, whereas by laser flash technique it is 0.18 Wm−1 K−1 for thermal conductivity. The importance of dislocation density and strain is discussed.
