Nano-enhanced Bio-based Phase Change Materials: A Brief Review

The high latent temperatures and variable melting points of bio-based phase change materials make them ideal for thermal control. This covers heat regulation for medical and pharmaceutical items, building comfort, and high-end electronics and automobiles. In recent years, research and application of energy-saving materials and technologies in buildings has increased strength. Modern construction technology aims to keep old and new structures energy efficient. TES employing PCMs is an energy-efficient approach. The use of bio-based PCMs in structures is achieving scientific and technical emphasis. Functional bio-PCMs improve building energy efficiency. Hydrogenated palm kernel fat, bio-phase change material (PCM). This bio-based PCM melted at 27.38 degrees C and had 80.52 J/g LHC. To catch PCM without leaks in a prepared matrix and use the composite-PCM for passive TES in building envelopes. This eco-friendly matrix is inexpensive. Clay and cellulose dominated PCMs. TGA demonstrated that the composite- PCM is thermally reliable. Graphite improved heat conductivity in Hot-Disk tests. FTIR confirmed chemical stability. SEM showed that impregnated matrix microstructure preserved bio-based PCM. Sustainability needs resource and energy efficiency. A Method for manufacturing of bio based PCM with Enhanced Nanoparticles Low heat conductivity means PCM hasn't been widely used. The two-step strategy is the most effective way to get ready for the NEBBPCM. In the first step of the two-step process, chemical or physical processes are used to make nanoparticles, nanofibers, and nanotubes.
