摘要：
Every year, the interest in obtaining new forms of phase change materials (PCM) and studying their physicochemical properties is growing. A topical task is to develop new experimental methods for studying the phase behavior of PCM. The paper presents the results of a study of the phase behavior of a nanosized aqueous dispersion of n-eicosane (C20H42) using an optical method. Samples of an aqueous dispersion of the studied paraffin were obtained using ultrasonic dispersion without adding surfactants. For the studied sample, the temperatures of phase transitions (melting, crystallization, rotator phases) were determined during heating and cooling. Phase transitions not observed in a bulk sample of the studied paraffin were discovered.
