Thermal Properties of Thin‐Film Polymers by Transient Heating

  author={Robin C. Steere},
The high‐temperature thermal properties of building material in thick slab form can be measured by a transient method reported earlier by Harmathy. The results here show the technique suitable for thin‐film polymers. Recently available ultrathin (0.00025 cm) constantan foil is shown capable of providing constant thermal flux. This foil reduces the original measurement time by two orders of magnitude, from 400 to 4 sec. Sample volume can be reduced at least 90%. Thermal diffusivity, thermal… CONTINUE READING
