Abstract
A hydrogel includes: a partially or fully ionized cationic polymer and at least one selected from the group consisting of a partially or fully ionized anionic polymer and a low molecular weight compound having two or more anionic groups; or a partially or fully ionized anionic polymer and at least one selected from the group consisting of a partially or fully ionized cationic polymer and a low molecular weight compound having two or more cationic groups; and water. The hydrogel can be used for for producing clay with viscoelastic properties.
Claims16
A hydrogel for producing clay with viscoelastic properties comprising:
- ionic compounds;
- a non-ionic polymer;
- and
- water,
- wherein the ionic compounds comprise:
- a cationic polymer and an anionic compound having two or more anionic groups, wherein the cationic polymer comprises a plurality of repeating units each having a cationic group, which is at least partially ionized;
- or
- an anionic polymer and a cationic compound having two or more cationic groups, wherein the anionic polymer comprises a plurality of repeating units each having an anionic group, which is at least partially ionized,
- wherein the cationic polymer is one or more selected from the group consisting of a cationic vinyl polymer, a cationic polysaccaharide and a cationic polypeptide, and the anionic polymer is one or more selected from the group consisting of an anionic vinyl polymer, an anionic polysaccharide and an anionic polypeptide,
- wherein a total molarity of cationic groups and a total molarity of anionic groups in the ionic compounds are different, and
- wherein a molecular weight of the non-ionic polymer ranges from 400 kDa to 800 kDa.
