스마트 페인트 응용 분야를 위한 조정 가능한 확산 반사율을 갖춘 n-옥타데칸 PCM

초록

Silica-encapsulated n-octadecane (ODS-1/2/3) nanocapsules were evaluated for smart-paint use combining latent-heat buffering with high diffuse reflectance. SEM reveals compact core–shell aggregates with reduced void fraction at higher core loading. Calibrated hemispherical DRS (200‒1500 nm) shows a scattering-dominated roll-off: SiO2 has the highest UV reflectance; all ODS maintain ~80‒83% in the visible, with shallow C‒H overtone dips near 1.4‒1.45 μm increasing with OD content. Encapsulation thus preserves visible brightness while adding thermal storage capacity.
