本研究主要以聚乙烯醇(PVA)與不同餵入比(0.5~1)的苯乙烯磺酸鈉(SSS)接枝共聚合成水膠,藉由小分子溶質(Benzoic acid,Vitamin K3 and Caffeine)在其水膠內通透過程,探討水膠結構和溶質對擴散行為的影響。在水膠結構方面,SSS接枝率越高,水膠平衡含水率也越高。水膠高分子體積分率越小,交聯點間平均分子量和高分子網目則越大。由於溶質通透主要受溶質在水膠內擴散行為和溶質在水膠網目內與鄰近高分子鏈的交互作用兩大影響,而實驗發現溶質大小對高分子網目大小比值(λ)越小,擴散速率越大,溶質在水膠內的繞曲度越小,但繞曲度比多孔硬物質中溶質擴散模型預測結果較大。溶質分子越大,溶解度越大,擴散及滲透速率越小。由結果得知溶質通透是由擴散控制。溶質擴散實驗結果與自由體積模型相比對,以擴散係數取自然對數與自由體積倒數的關係作圖,發現實驗結果的斜率比自由體積模型預測較小。在水膠中溶解度大的溶質其穩態吸附因子比在水膠中溶解度小的溶質較小,初始吸附因子隨著SSS的接枝率增加而增加,因為SSS為帶有離子性基團,會使水膠與溶質產生離子性作用,使得溶質受到吸附的影響。水膠網目越大,吸附越多,表面吸附作用對溶解度較差溶質較明顯。
Polyvinyl alcohol gels crosslinked with sodium styrenesulfonate(SSS) with SSS grafting ratio from 1.3×10-3 to 3.5×10-3 were prepared and drugs(Benzoic acid , Vitamin K3 and Caffeine)permeation and diffusion through gels were determined. The mesh size of gels were determined with hydrogel water contents(swelling)and elasticity data. The diffusion coefficients increase with swelling, and the solubility increases with drug size. Diffusion coefficient and solubility were presented in terms of the ratio of drug diameter to that of mesh size. The diffusion is a controlling step driving the permeation. The tortuosity of drug diffusion data in gels was calculated, which is significantly greater than the predicted value from the transport model in rigid porous media. This deviation is due to the complex structure of gels. Solute diffusion data are fitted with free volume model. We found that the slope of solute diffusion data versus the reciprocal of free volume is smaller than free volume estimation from the relation of ln(D/D0) and (1/H-1). In the hydrogels, the steady-state adsorption factors of the solutes with higher solubility is smaller than the solute with lower solubility. The initial adsorption factors increase with SSS grafting ratio, because SSS have ionic groups interacting with the solutes. The adsorption increase with the mesh size,and the surface adsorption has greater effect for the solute with lower solubility.
