Abstract
The present disclosure can provide aerogel compositions which have a thermal storage capacity, and which are durable and easy to handle. The present disclosure can provide aerogel compositions which include PCM coatings, particle mixtures, or PCM materials confined within the porous network of an aerogel composition. The present disclosure can provide methods for producing aerogel compositions by coating an aerogel composition with PCM materials, by forming particle mixtures with PCM materials, or by confining PCM materials within the porous network of an aerogel composition.
Claims29
An aerogel composition comprising aerogel material and phase change material.
A gel precursor solution comprising gel precursor materials and phase change materials.
A method of preparing an aerogel composition, comprising the steps of:
- a) providing a precursor solution comprising gel precursor materials and a solvent;
- b) incorporating a phase change material into the precursor solution;
- c) allowing the gel precursor materials in the precursor solution to transition into a gel composition comprising a gel framework and a corresponding network of pores within the gel framework, such that the phase change material is confined within the network of pores within the gel composition;
- d) extracting at least a portion of the solvent from the gel composition to obtain an aerogel composition.
