Abstract
Official abstract text for this publication.
There is provided a method for bonding together hydrogels by interposing a polyalkylene glycol between the gel surfaces to be bonded together of hydrogels. A method for bonding together hydrogels of the same type or different types, the method including: interposing a polyalkylene glycol between gel surfaces to be bonded together of the hydrogels and joining together the gel surfaces.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for bonding together same or different hydrogels, the method comprising: interposing a polyethylene oxide between gel surfaces to be bonded together of the hydrogels and joining together the gel surfaces, wherein the polyethylene oxide has a weight average molecular weight of 100,000 to 10,000,000. 2. The method for bonding together hydrogels according to claim 1 , wherein the hydrogels are each (i) a hydrogel comprising a water-soluble organic polymer (A) having an organic acid salt structure or an organic acid anion structure, a silicate salt, and a dispersant for the silicate salt, or (ii) a hydrogel comprising a water-soluble organic polymer (A′), which is different from the water-soluble organic polymer (A), and the silicate salt. 3. The method for bonding together hydrogels according to claim 2 , wherein the water-soluble organic polymer (A) is a water-soluble organic polymer having a carboxylate salt structure or a carboxy anion structure. 4. The method for bonding together hydrogels according to claim 3 , wherein the water-soluble organic polymer (A) is a fully neutralized or partially neutralized polyacrylate salt. 5. The method for bonding together hydrogels according to claim 4 , wherein the water-soluble organic polymer (A) is a fully neutralized or partially neutralized polyacrylate salt having a weight average molecular weight of 1,000,000 to 10,000,000. 6. The method for bonding together hydrogels according to claim 2 , wherein the water-soluble organic polymer (A′) is one or two or more compounds selected from the group consisting of polyacrylamide, cross-linked polyethylene glycol, and a poly(acrylamide-co-acrylate ester). 7. The method for bonding together hydrogels according to claim 6 , wherein the water-soluble organic polymer (A′) is poly(N-isopropylacrylamide) or poly(N,N-dimethylacrylamide). 8. The method for bonding together hydrogels according to claim 2 , wherein the silicate salt is a water-swellable silicate salt particle. 9. The method for bonding together hydrogels according to claim 8 , wherein the silicate salt is a water-swellable silicate salt particle selected from the group consisting of smectite, bentonite, vermiculite, and mica. 10. The method for bonding together hydrogels according to claim 2 , wherein the dispersant is a dispersant for a water-swellable silicate salt particle. 11. The method for bonding together hydrogels according to claim 10 , wherein the dispersant is one or two or more compounds selected from the group consisting of sodium orthophosphate, sodium pyrophosphate, sodium tripolyphosphate, sodium tetraphosphate, sodium hexametaphosphate, sodium polyphosphate, sodium poly(meth)acryl ate, ammonium poly(meth)acrylate, poly(sodium acrylate-co-sodium maleate), poly(ammonium acrylate-co-ammonium maleate), sodium hydroxide, hydroxylamine, sodium carbonate, sodium silicate, polyethylene glycol, polypropylene glycol, sodium humate, and sodium ligninsulfonate. 12. The method for bonding together hydrogels according to claim 1 , wherein the polyethylene oxide is a linear polyethylene oxide.
