HPC/23G/HEMA Hydrogel To improve the tensile strength and elongation at break, the hydrogels were ready To enhance the tensile strength and elongation at break, the hydrogels had been ready by adding HEMA, a well-known base material for soft make contact 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 from the dose, the gel fraction and Sw of your HPC/23G/HEMA hydrogels as a function in the dose, respectively. The gel fraction of the HPC/23G/HEMA hydrogels elevated with escalating respectively. The gel fraction on the HPC/23G/HEMA hydrogels elevated with rising dose, as shown in Figure 6a. The substantial boost in the gel fraction shifted for the dose, as shown in Figure 6a. The substantial enhance within the gel fraction shifted for the greater dose side with an increase in HEMA concentration. This recommended that HEMA larger dose side with a rise in HEMA concentration. This recommended that HEMA inhibited the Nicarbazin Protocol crosslinking reaction of HPC as the main element, especially in the low inhibited the crosslinking reaction of HPC because the primary element, particularly within the low dose variety. In contrast, the Sw on the HPC/23G/HEMA hydrogels decreased steadily dose range. In contrast, the Sw with the HPC/23G/HEMA hydrogels decreased progressively with increasing concentrations. The Sw on the HPC/23G/HEMA hydrogels at greater than with increasing concentrations. The Sw of the HPC/23G/HEMA hydrogels at greater than 30 kGy was independent in the HEMA concentration and was just about the same. However, 30 kGy was independent from the HEMA concentration and was virtually exactly the same. Having said that, at 10 and 20 kGy, Sw improved with increasing concentration of HEMA due to the at 10 and 20 kGy, Sw increased with escalating concentration of HEMA as a result of the lower inside the crosslinking density. lower within the crosslinking density.(a)(b)Figure 6.
