  • 本研究之主要利用聚乙烯醇(polyvinyl alcohol)及聚丙烯酸(polyacrylic acid)製作離子交換膜,並摻入奈米金,製得不同摻混比例之PVA/PAA-Au薄膜。
    奈米金利用化學還原法並加入11-氫硫基醇(11-mercapto-1 - undecanol),製作使其帶有硫醇官能基來對奈米金進行化學吸附,接下來再利用奈米金周圍的硫醇官能基與PVA/PAA之官能基進行化學吸附,所以奈米金與PVA/PAA間具有非常強的做用力,而能發揮出奈米金的最大效能。
    奈米金的鑑定利用粒徑分析儀、UV-Vis 光譜分析、FT-IR 光譜分析、SEM證明出本研究所備製的奈米金之性質。
    PVA/PAA以不同比例6:4、8:2、10:0進行摻混,並加入不同重量百分比之奈米金0.1 wt%、0.3 wt%製成PVA/PAA-Au複合薄膜,利用X-ray、FT-IR 光譜分析進行結構分析,TGA進行熱性能分析、應力-應變測試、導電性質分析、離子交換容量(IEC)、化學穩定度、含水性分析。
    經實驗結果顯示PVA/PAA比例6:4、8:2因具有較大的交聯度,故機械強度強、化學穩定度佳、熱性質佳,且有PAA的加入可增加離子交換容量及導電性。
    奈米金的加入會使薄膜之性質改變,奈米金可以增加薄膜之機械性質、吸水膨潤度、導電性、離子交換容量(IEC),化學穩定度在6:4、8:2沒有明顯增加,在10:0可提升10%的殘留率。


    In this study,main utilize polyvinyl alcohol (PVA) and polyacrylic acid (PAA) make ion exchange membranes. Mix and gold nanoparticles to make different PVA/PAA membrane which admix the proportion.
    PVA is regarded as the main body of the ion exchange membranes,utilize PVA membrane to have higher alternative characteristics to water,and apply to the separation system of water / alcohol,and then improve the ion conductivity of the membrane with PAA. And mix the gold nanoparticles with sulfur-hydroxyu (thiol groups) groups probe into the properties of the membrane.
    Gold nanoparticles make use of chemical reduction method and join the 11-mercapto-1-undecanol . Make thiol groups to afoot chemical adsorption to gold nanoparticles,and subsequently utilize the thiol groups of circumambiency gold nanoparticles afoot chemical adsorption with PVA/PAA funtional groups. So gold nanoparticles and PVA/PAA have very strong attractiveness, and can ergonomically to the gold nanoparticles greatest efficiency.
    The gold nanoparticles exploitation the laser paticle size analyzer、UV-Vis spectrum、FT-IR spectrum、Transmission electron microscope,Prove is characteristic of this research prepared gold nanoparticles.
    PVA/PAA admix in different proportions at 6:4, 8:2, 10:0,and to join gold nanoparticles 0.1 wt%, 0.3 wt% of different weight percentages to make PVA/PAA - compound membrane. Utilize X-ray, FT-IR spectral analysis proceed to structural analysis,TGA, DSC proceed to the thermal analyses,stress-strain curve analysis,conductive property analysis,ion exchange capacity analysis (IEC),stability of chemistry analysis,water uptake analysis.
    Revealed PVA/PAA has great cross-linking at proportion 6:4、8:2 by the experimental result,so superior of mechanical intensity、stability of chemistry degree、thermal character. And there is joining of PAA that can increase ion exchange capacity analysis (IEC) and conductive degree.
    Gold nanoparticles joining will change of the membrane properties,joining of Gold nanoparticles that can increase mechanical intensity、water uptake、conductive degree、ion exchange capacity (IEC). The steady degree of chemistry has not obviously increased at 6:4, 8:2,but can improve 10% of the residue rate at 10:0.
