Superabsorbent Polymers (SAP) can be classified from different perspectives: 1. Morphological Structures: SAP can be categorized as powders, particles, fibers, spheres, emulsions, and membranes. These structural variations are designed to meet diverse application requirements. For example, powders can be used in the production of sanitary napkins and diapers by incorporating them into multi-layered sheets. Spherical products and particles are suitable for deodorant applications. Fiber-based SAP are used to create antistatic electric fibers, while membranes find use in anti-frost sheets. Emulsion forms are preferred for soaking and painting applications. 2. Sources: SAP can be classified into three main categories based on their sources: a. Natural macromolecules, including polysaccharide-based and polypeptide-based materials. Polysaccharide-Based SAP, such as cellulose, starch, chitin, chitosan, and natural gums (e.g., xanthan, guar, a...
