Abstract
A method and apparatus for producing a superabsorbent foam is provided. The method includes forming a reaction mixture comprising at least one compound capable of forming a superabsorbent foam, stirring the reaction mixture, applying mechanical waves to the reaction mixture and repeating the stirring and applying a selected number of times thereby forming the superabsorbent foam.
Claims18
A method for producing a superabsorbent foam comprising the steps of:
- a. forming a reaction mixture comprising at least one compound capable of forming a superabsorbent foam;
- b. stirring said reaction mixture;
- c. applying mechanical waves selected from the group consisting of sonic and ultrasonic waves to said reaction mixture;
- and
- d. repeating said steps of stirring and applying mechanical waves a selected number of times thereby forming said superabsorbent foam.
A porous superabsorbent foam substantially comprised of cross-linked collagen, wherein said cross-linked collagen is formed by applying mechanical waves selected from the group consisting of sonic and ultrasonic to a stirred reaction mixture during a cross-linking reaction, said reaction mixture comprising at least collagen and a cross-linking agent.
A method for producing a superabsorbent foam comprising the steps of:
- a. forming a reaction mixture comprising at least one compound capable of forming a superabsorbent foam;
- b. stirring said reaction mixture;
- and
- c. sonicating said reaction mixture with sonic waves and/or ultrasonic waves while reacting said reaction mixture to form a superabsorbent foam.
A method for producing a superabsorbent polymer, the method comprising the steps of:
- a. forming a reaction mixture comprising at least one compound capable of forming a superabsorbent polymer;
- b. stirring.said reaction mixture;
- and
- c. sonicating said reaction mixture with sonic waves and/or ultrasonic waves while reacting said mixture to form said superabsorbent polymer.
