Preparation and Thermal Conductivity of Graphene/N-octadecane Composite Phase Change Materials
摘要
Abstract
Using N-octadecane as a matrix,graphene,a nanomaterial with excellent thermal conductivity,was introduced by mechanical mixing method,and graphene/N-octadecane composite phase change materials with different mass fractions were prepared to enhance the thermal conductivity of the matrix N-octadecane.Graphene/N-octadecane composite phase change materials with different mass fractions were experimentally prepared and tested for physicochemical characterization and thermal conductivity.The experimental results show that the thermal conductivity of the composites is enhanced with the increase of graphene mass fraction.When the mass fraction of graphene was 1.5％,the solid and liquid thermal conductivities of the graphene/N-octadecane composite phase change material reached 0.33 W/(m·K) and 0.19 W(/m·K),respectively,which was an increase of 83.3％ in solid thermal conductivity and 18.7％ in liquid thermal conductivity compared to pure N-octadecane.These results indicate that graphene as a thermal conductivity enhancer can effectively improve the thermal conductivity of phase change materials,especially in the solid state.关键词
