How does the inclusion of phase change materials (PCMs) in WPC regulate tree box temperature?

The integration of phase change materials (PCMs) into wood-plastic composites (WPC) offers an innovative solution for regulating tree box temperature in urban environments. PCMs absorb, store, and release thermal energy during phase transitions, effectively stabilizing temperature fluctuations. When embedded in WPC, these materials help maintain optimal root zone conditions by mitigating extreme heat or cold, promoting healthier tree growth. This thermal regulation reduces stress on urban trees, enhancing their survival rates in challenging climates. Additionally, WPC's durability combined with PCMs' energy efficiency creates a sustainable solution for urban greening projects, contributing to cooler and more resilient cities. The synergy between these materials demonstrates the potential of smart composites in advancing eco-friendly urban infrastructure.
