Abstract :In this study, n-dodecanol and 1-tetradecanol were nanoencapsulated by polyinsert ignore into journalissuearticles values(methyl metharcylate-co-methacrylic acid); insert ignore into journalissuearticles values(pinsert ignore into journalissuearticles values(MM-co-MA);); wall using emulsion polymerization method which was defined as one-stage insert ignore into journalissuearticles values(OS); or two-stage insert ignore into journalissuearticles values(TS);. Nanocapsules were analyzed by Fourier-transform infrared insert ignore into journalissuearticles values(FT-IR); spectroscopy, transmission electron microscopy insert ignore into journalissuearticles values(TEM);, differential scanning calorimeter insert ignore into journalissuearticles values(DSC); and thermogravimetric analyzer insert ignore into journalissuearticles values(TGA);. According to the analyses results, typical core-shell structured, spherical shaped, uniform nano-sized particles having high thermal stability and energy storage capacity were fabricated successfully. Enthalpy values of the nanocapsules prepared by TS process were higher and reached up to 171 J/g. It was concluded that thermal degradation stability of the nanocapsules could be improved using TS emulsion polymerization method. Besides, in the study, the nanocapsules were incorporated in polyacrylonitrile nanofibers using co-axial electrospinning method and composite nanofibers having 19 j/g energy storage capacities were produced. The prepared core-sheath structured nanofibers surfaces were rough and coarse but diameter distribution was unimodal.
