Preparation and Properties of Polyethylene Glycol-Based Composite Phase Change Materials
Abstract
This paper aims to improve the small temperature range and poor heat-conducting property of polyethylene glycol (PEG) in practical use. One side, two different PEGs which have different phase change temperatures are mixed, in order to wider the temperature range; another side, the thermal conductivity was improved by adding graphite into composite. The structure characteristics and thermal property of composite were measured and studied. Thermal infrared imager is used to measure the practical effect of temperature-control, by coating composite on fabrics.
