http://www.cybercolloids.net/information/technical-articles/pectin-basics-gelling-properties-and-applications WebAbstract. Hydrogels are degradable polymeric networks, in which cross-links play a vital role in structure formation and degradation. Cross-linking is a stabilization process in polymer chemistry that leads to the multi-dimensional extension of polymeric chains, resulting in network structures. By crosslinking, hydrogels are formed into stable ...
