月桂酸-膨胀石墨复合相变材料的制备及性能
Preparation and performance of lauric acid-expanded graphite composite phase change materials
摘要
Abstract
The lauric acid-expanded graphite (LA/EG) composite phase change materials was prepared by using adsorption properties of porous graphite with lauric acid as phase change material, porous expanded graphite(EG) as the skeleton carrier; and through the experiment of the basic properties of shape stabilized phase change material, surface morphology, durability were studied. The results showed that lauric acid was effectively encapsulated within the pores of the expanded graphite; phase change temperature and latent heat of LA/EG was 45.45℃and 125.30 J·g?1 respectively whenmLA:mEG=95:5. LA/EG loss rate was very small after 100 times of hot and cold cycle phase transitions, which indicated that LA/EG has good stability in practice.关键词
