Description

Application

• Epoxy⁻PCM Composites with Nanocarbons or Multidimensional Boron Nitride as Heat Flow Enhancers.: This study explores the application of epoxy⁻phase change material (PCM) composites integrated with nanocarbons or multidimensional boron nitride to enhance heat flow properties. n-Nonadecane is used as a PCM due to its suitable thermal properties, demonstrating its potential in improving the efficiency of thermal management systems (Agrawal et al., 2019).
