高吸水性树脂吸水机理的探讨

Study on water absorbing mechanism of absorbent resin

高吸水性树脂是高分子电解质，具有三维网络结构，其显著的特点是高吸水性能和高保水性能。应用ＦｌｏｒｙＨｕｇｇｉｎｓ热力学理论和溶液热力学理论对高吸水性树脂的吸水机理进行了探讨；同时，从高分子结构角度对吸水机理亦进行了理论探讨。

Super absorbent resin was a three dimensional network polymer, which was electrolyte. It can absorb several hundred even more than thousand times of water as much as its own weight, owning to its high capacity for absorbing water, high capacity of water retention under pressure. Absorbing water mechanism of super absorbent resin was studied by thermodynamic theory of Flory Huggins and thermodynamic theory of solution, and macromolecular structure.
