In this study, microencapsulated phase change materials (MEPCM) were imparted into nanofibers using electrospinning method and an original material composite systems, microparticles interconnected through nanofibers were produced. Poly(methyl methacrylate-co-ethylene glycol dimethacryate-co-2-hydroxyethyl acrylate) and poly(methyl methacrylate-co-ethylene glycol dimethacrylate-co-2-hydroxyethyl methacrylate) shells and n-octadecane and Rubitherm RT-21 core were formed for this study. Composites with low diameter nanofibers as compored to microparticles consisted of polyacrylonitrile (PAN) nanofibers and dispersed MEPCMs together. MEPCMs were produced through commonly used emulsion polymerization technique. They were dispersed into PAN solution in dimethylformamide (DMF) and electrospinned. Thermophysical properties of MEPCMs dispersed nanofibers were determined using differential scanning calorimetry (DSC) as Fourier Transform Infrared (FTIR) Spectroscopy instrument was used to prove copresence of core, shell, and nanofiber materials. Besides, Scanning Electron Microscopy (SEM) device was used to examine the morphology of MEPCMs and the MEPCM nanofiber composites.
