摘要註:	聚苯乙烯以不同比例之硫酸乙醯(Acetyl sulfate)試劑進行磺酸化反應，形成磺酸化程度在4.36 mol% 至36.69 mol% 間的磺酸化聚苯乙烯(Proton polystyrene-sulfonate, PSSH)。以交流阻抗法分析不同磺酸化程度之磺酸化聚苯乙烯之導電度，由結果可以發現，隨著磺酸化程度由4.36 mol%增加至36.69 mol%，PSSH薄膜之電導係數由5.7×10-4 Scm-1增加至2.3×10-2 Scm-1。電流式氣體感測裝置是將黃金濺鍍於多孔性氧化鋁薄膜上形成三電極式，並鋪以25.84 mol% PSSH薄膜為電解質製備而成。氣體感測模式為氣體經過薄膜電解質的選擇，到達電極反應，去離子水經由多孔性氧化鋁薄膜，提供PSSH之濕度並維持其導電度。結果顯示，氣體流速100 ml/min，工作電位750mV(vs. Au-QRE)時，在濃度為100 ppm至600 ppm的範圍內，二氧化氮的應答呈現良好的線性關係。二氧化氮感測的靈敏度為109.4 nA/cm2. ppm。 A family of proton polystyrenesulfonate(PSSH) membranes was synthesized using polystyrene and acetyl sulfate. The extent of sulfonation varies from 4.36 to 36.69 mol%. The conductivity of PSSH films of various contents of sulfonation was measured using AC Impedance method. The results showed that the conductivity coefficient varied from 5.7×10-4 Scm-1to 2.3×10-2 Scm-1as the sulfonation content varied from 4.36 mol% to 36.69 mol%. The sensing assembly was fabricated by sputtering Au onto the masked surface of a porous aluminum oxide substrate (Anopore®), followed by coating a thin film of PSSH film as the electrolyte. The amperometric measurement of this sensing device was performed by conducting the gas stream directly toward the PSSH film while water storaging in the back side of Anopore® to provide the suitable humidity for the PSSH membrane. The calibration curve of 100~600 ppm NO2 was linear and the sensitivity was 109.4 nA/cm2ppm, under the conditions of gas flow of 100ml/min and working potential of 750mV(vs. Au-QRE).
