摘要

The heat-regulating properties of polyacrylonitrile films with added microcapsules containing paraffin were studied. The difference in the surface temperatures of films without paraffin and with added (5 wt% and more) microcapsules reached 15-20°C upon heating to 100°C. Conversely, the heat accumulated by the fused paraffin was released during cooling of the films. The surface temperatures of the films equilibrated after the paraffin solidified.
