Abstract
The present disclosure provides for a hybrid salogel, methods of making hybrid salogels, and systems using hybrid salogels.
Claims20
A hybrid salogel comprising:
- a phase change material (PCM), wherein the hybrid salogel includes about 94 to 99 weight percent of the PCM;
- a polymer mixture comprising a first polymer and a second polymer, wherein the first polymer is selected from the group consisting of:
- a polyvinyl alcohol (PVA), a copolymer of PVA, and a homopolymer containing a plurality of hydroxyl groups, wherein the second polymer is polyacrylamide (PAAm) or a copolymer of PAAm, wherein the hybrid salogel includes about 0.2 to about 5 weight percent of the polymer mixture;
- and
- a crosslinker, wherein the hybrid salogel includes about 0.1 to 0.5 weight percent of the crosslinker.

A method for preparing a hybrid salogel, the method comprising:
- adding a polymer powder into a liquid phase change material (PCM) to form a mixture, wherein the polymer powder comprises polyvinyl alcohol (PVA) and polyacrylamide (PAAm);
- dissolving the powder in the liquid PCM and forming a homogeneous solution;
- gelling the homogeneous solution;
- and
- dissolving the polymer powder into water followed by dissolving a desired quantity of anhydrous salt into a liquid, forming a homogeneous solution.
