Cellulose beads were successfully prepared from waste denim using a dissolution-regeneration approach with ionic liquids as the dissolving solvent. Cellulose beads with different morphologies were achieved by altering the dissolving and coagulating solvents. The morphological differences were quantified by N physisorption. The impact of morphology on the cellulose beads' potential application was investigated in the context of drug loading and release. The results show that the fibrous morphology showed a better loading capacity than the globular analogue due to its higher surface area and pore volume.
以离子液体为溶解溶剂，采用溶解-再生法成功地从废旧牛仔布中制备出纤维素珠。通过改变溶解溶剂和凝固溶剂，获得了具有不同形态的纤维素珠。通过N物理吸附对形态差异进行了量化。在药物负载和释放的背景下，研究了形态对纤维素珠潜在应用的影响。结果表明，由于纤维状形态具有较高的表面积和孔体积，其负载能力优于球状类似物。
