WebApr 11, 2024 · If the CFC is hydrophilic, the wetted CFC may stick to the skin, although the sweat can be absorbed by the CFC. On the other hand, the hydrophobic CFC can, to a great degree, prevent the diffusion of the sweat outward, and thus the sweat cannot be quickly expelled out from the skin. In both cases, the comfort is greatly sacrificed. WebThe hydrophilic nature of chitosan makes it a suitable starting material for use in biodegradable and biocompatible hydrogels. ...
