Exploring thermal dynamics of polyaniline-modified paraffin wax phase change material with varied PANI loadings (1?4% wt.)
In this experimental study, we explore the potential enhancements in thermal conductivity while investigating alterations in latent heat and phase change temperature within Composite Phase Change Materials (PCMs). These composites consist of Paraffin Wax (PW) as the base material, incorporating disp...
