    I was just wondering whether anyone knows the answer to a question that has appeared on the PH1004 paper 3 times in the last 4 years. The question is ' which 3 different types of colloidal structures can be commonly found in hydrogels?' Any help would be much appreciated.

    I'm not 100% certain but I believe the answer would be:

    Linear networks involving water and a gelling agent
    Isogels; gelling agent chemically similar to bulk liquid
    Heterogels; gelling agent chemically dissimilar to bulk liquid

    Cross-linked polymers (Which are usually organic in nature hence chemically dissimilar to water)
