알케인 사슬 길이가 SiO2로 캡슐화된 PCM의 형태적 특성에 미치는 영향

초록

This study compares the morphology of two SiO2-encapsulated alkanes at the same core-to-shell ratio,1:1.We have analyzed PS-1 (paraffin) and ES-1 (n-eicosane). Both have been synthesized by sol-gel routes and characterized by SEM. Particles are largely spherical, with mean diameters near 200-250 nm. PS-1 has shown stronger agglomeration and rougher surfaces. ES-1 has exhibited polydispersity and coarse shells. Synthesis temperature and alkane chain identity likely affect droplet stability, shell growth, and particle size distribution. Results suggest chain length and purity can tune emulsion behavior and shell uniformity at fixed core-to-shell ratio.
