Abstract

A method for producing a form-stable phase-change material to nucleate sugar alcohols includes directionally freezing a slurry of solid chitosan and solvent and additives, providing a frozen slurry including unidirectional pillars of frozen solvent that force suspended solid particles into interstices, exposing the frozen slurry to conditions causing sublimation of the solvent of the frozen slurry to remove frozen solvent and provide a body having pillars of vacancies therein, sintering the body to provide a scaffold including the pillars of vacancies therein, graphitizing the scaffold by heating in argon, treating the scaffold with aqueous base, and adding a molten sugar alcohol phase-change material to the scaffold such that the molten phase-change material is drawn into the pillars of vacancies by capillary action to provide the form-stable phase-change material having reduced hysteresis of the melting point of the sugar alcohol phase-change material.
