Polyelectrolyte-surfactant hydrogels – preparation, properties.
Original language description
Oppositely charged polyelectrolytes and surfactants can form hydrogel-like materials at suitable conditions. Surfactant concentration should be sufficiently high, well above its critical micelle concentration. Micelles are supposed to form crosslinking points by electrostatic interactions with the oppositely charged groups on the polyelectrolyte chain. These materials are attractive as carriers of hydrophobic species within a hydrophilic matrix. This contribution illustrates variety of different components which can form such materials and some of their properties. Negatively charged hyaluronan was used as a representative of biopolymeric polyelectrolyte and positively charged Septonex surfactant as its reaction partner. Chitosan and aminated dextrane were used as positively charged polyelectrolytes and combined with several anionic surfactants – SDS, linear and branched STS. The formation of gels was tested in a broad concentration region and visualized using a hydrophobic dye Oil red O, which in th
