水凝胶光固化时间优化：AAm与LAP浓度影响机制研究

1.3 Properties and Structural Characterization of Hydrogels 1.3.1 Photocuring Time In this experiment, the effects of acrylamide (AAm) and lithium phenyl-2,4,6-trimethylbenzoylphosphinate (LAP) on the photocuring time of hydrogels were investigated by varying their percentages of the total solid mass (%). The experiments were conducted at room temperature: a 405 nm light source (1.22 mW/cm²) was used to irradiate the precursor solutions from a distance of 10 cm. The curing endpoint was determined using the test tube tilt method, and the curing time was recorded. Each experimental condition was tested in triplicate, and the results were averaged.
