Abstract
The present disclosure relates to a method of preparing a hydrogel comprising: (i) Preparing a mixture of a water-soluble polymer, an inorganic acid, and radiation-reflecting inorganic particles; (ii) Adding a cross-linking agent to the mixture to form a hydrogel precursor; (iii) Freezing and thawing the hydrogel precursor, thereby forming a hydrogel, wherein the hydrogel precursor comprises: about 5wt% to about 30wt% of a water soluble polymer; about 0.3wt% to about 2.5wt% of a mineral acid; about 0.05wt% to about 0.5wt% of a crosslinking agent; and about 3wt% to about 70wt% of radiation reflective inorganic particles, wherein wt% is based on the total weight of the hydrogel precursor. The present disclosure also relates to hydrogel precursors and hydrogels obtained by the methods disclosed herein. The present disclosure also relates to hydrogels comprising: about 5wt% to about 30wt% of a water soluble polymer; about 0.1wt% to about 1.5wt% of a crosslinking agent; and about 3wt% to about 70wt% of radiation reflective inorganic particles, wherein wt% is based on the total weight of the hydrogel.
