Synthesis, optimization, characterization, and potential agricultural application of polymer hydrogel composites based on cotton microfiber

The optimum content of cotton microfiber, initiator, cross-linker, and sodium hydroxide were determined using the central composite design method. Polymer hydrogels (PHGs) were characterized using Fourier-transform infrared (FT-IR), scanning electron microscopy, and thermal gravimetric analysis. A c...
