Claims78
A wound dressing comprising an absorbable polyelectrolyte material and ionic crystals, wherein a weight percent of ionic crystals in the absorbable polyelectrolyte material is at least about 5% w/w of an overall weight.
A method of making a wound dressing, comprising:
- treating cellulose with an alkali solution;
- mixing the alkali solution with a chloracetic acid (CAA) solution to form a saturated sodium chloroacetate (NaCAA) solution, wherein ionic crystals are formed in the NaCAA solution;
- and
- treating the cellulose with the NaCAA solution to form carboxy methyl cellulose (CMC) having embedded ionic crystals, wherein a weight percent of ionic crystals in the absorbable polyelectrolyte material is at least about 5% w/w of an overall weight.
A method of making a wound dressing, comprising associating an absorbable polyelectrolyte material with ionic crystals, wherein a weight percent of ionic crystals associated with the absorbable polyelectrolyte material is at least about 5% w/w of an overall weight.
