中文摘要
本實驗的目的主要是利用有機物4-methoxycinnamic acid(MCA)與無機物二氧化鈦進行物理性混掺與化學性鍵結,藉由4-methoxycinnamic acid(MCA)對UVB的吸收與TiO2在UV光的部份吸收與物理性反射,進而大幅提升整體UV吸收效果。在結構的鑑定上與吸收效果上,從FT-IR、UV-VIS、XRD及Raman光譜等儀器量測到官能基與最大吸收波峰等性質變化中,確定了二氧化鈦的銳鈦礦結構比起無定型結構來在UV吸收上來的有效率。在不同呎吋的比較中,利用相同莫耳比TiO2/MCA混掺到溶劑中,所獲得的結果為小呎吋的混掺溶液具最佳UV吸收效果。同時在進行長時間曝光的比較,在物理混掺的溶液中,相同呎吋的銳鈦礦結構在離心過後其MCA的濃度小於無定型結構。在化學鍵結上,以Raman光譜取得Ti-O-C的特徵峰(約在1070 cm-1)證明其鍵結的出現。並輔以FT-IR的圖譜說明有少許的MCA依舊未鍵結或產生酯類(1100 cm-1、1300 cm-1),這是還要在改進的地方。並在UV圖譜中可以發現TiO2/MCA無論在物理混掺或化學鍵結中受到TiO2影響,都有隨顆粒大小增減吸收值的趨勢。
Abstract
The goal of this experiment is to explore the absorption and reflection of UV light by TiO2/MCA in physical mixing and chemical synthesis. The experiment shows that TiO2/MCA in anatase structure is better than in amorphous structure (with FT-IR. UV-VIS. XRD and Raman spectrum).
The first experiment shows that the small TiO2 particle size (290 nm) has better UV absorption than large TiO2 particle (400 nm) in the same mole. After TiO2/MCA(P) exposed to the UV source, the concentration of MCA in TiO2 anatase structure will decrease much than in TiO2 amorphous structure.
In the second experiment, the raman peak in 1070 cm-1 proofs that the existence of the Ti-O-C structure. In addition, the FT-IR spectrums peck shows a part of TiO2/MCA has no chemical bonding, and also produces sparse ester (1100 cm-1 . 1300 cm-1). If the peak (1100 cm-1 . 1300 cm-1) were not exist, compare with the previous step, the level of chemical bonding will increase, and it will produce even less ester.
In conclusion, The direction of UV absorption of TiO2/MCA(C1. C2. C3) and TiO2/MCA(P) are extremely similar.
