WebApr 3, 2024 · In addition, by adding glycerin to the dispersion medium, hydrogel retain water for a long time and remain flexible at low temperature. The hydrogel contains an ionizable polymer electrolyte, sodium polystyrene sulfonate, so it has outstanding electrical conductivity (0.36 s/m). Glycerol , also called glycerine in British English and glycerin in American English, is a simple triol compound. It is a colorless, odorless, viscous liquid that is sweet-tasting and non-toxic. The glycerol backbone is found in lipids known as glycerides. Because it has antimicrobial and antiviral properties, it is widely used in … See more Although achiral, glycerol is prochiral with respect to reactions of one of the two primary alcohols. Thus, in substituted derivatives, the stereospecific numbering labels the molecule with a sn- prefix before the stem name of … See more Glycerol is generally obtained from plant and animal sources where it occurs in triglycerides, esters of glycerol with long-chain carboxylic acids.
