HPC/23G/HEMA Hydrogel To enhance the tensile strength and elongation at break, the hydrogels had been prepared To improve the tensile strength and elongation at break, the hydrogels have been ready by adding HEMA, a well-known base material for soft get in touch with lenses. Figure 6a,b show by adding HEMA, a well-known base material for soft get in touch with lenses. Figure 6a,b show the gel fraction and Sw from the HPC/23G/HEMA hydrogels as a function of your dose, the gel fraction and Sw with the HPC/23G/HEMA hydrogels as a function with the dose, respectively. The gel fraction with the HPC/23G/HEMA hydrogels enhanced with escalating respectively. The gel fraction on the HPC/23G/HEMA hydrogels enhanced with increasing dose, as shown in Figure 6a. The substantial enhance within the gel fraction shifted for the dose, as shown in Figure 6a. The substantial enhance inside the gel fraction shifted towards the higher dose side with a rise in HEMA concentration. This suggested that HEMA higher dose side with a rise in HEMA concentration. This recommended that HEMA inhibited the crosslinking reaction of HPC as the most important element, in particular in the low inhibited the crosslinking reaction of HPC because the key element, specifically in the low dose range. In contrast, the Sw in the HPC/23G/HEMA hydrogels decreased gradually dose range. In contrast, the Sw of the HPC/23G/HEMA hydrogels decreased steadily with rising concentrations. The Sw of the HPC/23G/HEMA hydrogels at higher than with rising concentrations. The Sw on the HPC/23G/HEMA hydrogels at greater than 30 kGy was independent of your HEMA concentration and was virtually the same. Nevertheless, 30 kGy was independent in the HEMA concentration and was nearly the identical. Having said that, at ten and 20 kGy, Sw elevated with growing concentration of HEMA due to the at ten and 20 kGy, Sw improved with increasing concentration of HEMA due to the decrease in the crosslinking density. reduce inside the crosslinking density.(a)(b)Figure six.
