    Abstract: A method for producing foams, such as sponges, from hydrocolloids is described. A solid or semi-solid gel is formed by dissolving polymeric material in an aqueous solvent. The gel formed is allowed to set, and may optionally then be cut into the desired shape. The gel may be frozen to allow formation of ice crystals to act as porogens. Subsequently, the gel is exposed to a radiant energy field for drying under vacuum. This causes the solvent to boil and the foam or sponge is formed. Medicinally active ingredients may be included in the process, so that the sponge or foam formed contains the active ingredient dispersed within the structure. The method described provides an alternative to the conventional methods of particulate leaching or freeze drying.

    Abstract: The present invention provides a conducting polymer, a synthesis method thereof, and an electroactive electrode covered with the said conducting polymer. The conducting polymer is synthesized as follows: use the polybasic acid as dopant and crosslinking agent, and polymerize monomers into conducting polymer hydrogel. The monomers are selected one or more from pyrrole or its derivatives, thiophene or its derivatives, aniline or its derivatives. The acid group of the polybasic acid contains phosphate or polybasic acid which contains at least two substituents per molecule selected from sulfate, nitrate or carboxylic in which the molecular weight of at least one acid group is no more than 800. The mole ratio of the acid group in polybasic acid to monomers of the conducting polymer is 1:12-12:1. The preparation applied in the invention is simple, and need not to import any impurity. The conducting polymer hydrogel has high ionic conductivity, super hydrophilicity, and good biocompatibility.
