纳米石墨烯片-石蜡复合相变蓄冷材料制备方法及热物性研究
Preparation and thermal properties of nano-GnPs as stuffing into the cool storage phase change materials
摘要
Abstract
Because of its good thermal property,nano-graphite (nano-GnPs)materials has became a research hotspots.The best adding a-mount of polyester type dispersant of dispersed system of nano-GnP-sparaffin composite phase change materials (PCMs)was 2% by me-chanical and chemical modification methods with nano-GnPs as stuff-ing.The stable uniform dispersion of composite PCMs was obtained by precipitation and separation.The adding amount of nano-graphene had no effect on the starting and termination points and peak of phase change.However,the adding amount of nano-GnPs will lower the phase change latent heat of composite PCMs in some degree.Phase change latent heat of composite PCMs was 0.7% higher than pure paraffin when the adding amount of nano-GnPs was 1 .5%. Moreover,a good stability in the process of circulation with nano-GnPs as stuffing was found in composite PCMs.关键词
