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.
Claims23
An aerogel composition which has a latent thermal storage capacity, wherein
- the aerogel composition comprises a monolithic aerogel material, a fibrous reinforcing material, and an encapsulated phase change material,
- the monolithic aerogel material comprises a gel framework and a corresponding network of pores integrated within the gel framework,
- the encapsulated phase change material is nanoconfined within the network of pores within the monolithic aerogel material,
- the aerogel composition has a thermal conductivity of 25 mW/m-K or less at 37.5° C. and ambient pressure, and
- the encapsulated phase change material in the aerogel composition comprises 50 wt % or less of the total solids.
