| Fig. 1(c) shows that the increase in the concentration of the cross-linking agent NMBA resulted in the initial increase, and then decrease of the swelling capacity of the resin. This result was observed because when the cross-linker concentration is too low, the cross-linking density of the resin would also be low, which causes the formation of a sparse three-dimensional network that facilitates water entry. Moreover, the adsorption ability decreased, and the solubility of the material increased on a macroscopic perspective, which led to a decrease in water absorbency. This decrease has direct effects on the hydrogel strength after swelling. The resin did not become an elastic gel but a colloid with low strength. The swelling ability of the resin was reduced. |

| 圖1(c)表明,增加交聯(lián)劑NMBA的濃度一開始引起樹脂溶脹力的升高,但繼后降低。觀察到這個結(jié)果是因?yàn)楫?dāng)交聯(lián)劑的濃度過低,樹脂的交聯(lián)密度也將是低的,這將導(dǎo)致形成一些稀疏的三維網(wǎng)絡(luò),這些網(wǎng)絡(luò)促進(jìn)水的進(jìn)入。此外,從宏觀角度來看,吸附能力降低,以及材料的溶解度增加,會導(dǎo)致吸水率降低。而吸水率的降低又對溶脹后凝膠強(qiáng)度有直接的影響。(此種條件下)樹脂并非成為一個具有彈性的凝膠,而是低強(qiáng)度的膠體。樹脂的溶脹能力降低。 |
