Predicting large comprehensive refrigeration performance of plastic crystals by compositing carbon architectures for room temperature application
Plastic crystals PE (pentaerythritol) possess colossal barocaloric effect (BCE) that is promising for solid-state refrigeration; however, the high phase transition temperature (> 400 K) and low thermal conductivity (
