Abstract
As a two-dimensional material, graphene shows excellent properties in many aspects. Among them, it exhibits extremely high carrier mobility, excellent thermal conductivity, and high temperature stability due to its unique lattice structure, so it is superior than previously used conventional materials in the field of thermal applications. This paper introduces the study of graphene heating film of centimeter scale. We transfer large areas of graphene films to four different substrates to study the characteristics of heating temperature, thermal response time and heating uniformity of graphene films. Experimental results show that graphene with a heating area of 0.7cm × 1cm can be rapidly raised from room temperature to above 100℃ at a DC voltage of 25V. According to the experimental results, graphene performs well in both heating temperature and heating rate compared to traditional heating materials, which provides good prospects for the use of graphene in fields such as deicing, defogging, medical physiotherapy and others.
