本研究製備環氧壓克力樹脂/鎢錯合物抗近紅外線混成材料，藉由添加鎢錯合物的方式改善一般抗近紅外線薄膜吸收範圍狹窄、吸收效果不佳等問題。 因此研究中分別探討不同配位劑對鎢錯合物近紅外光吸收強度的影響，以及使用溶劑對反應所產生的溶劑效應。在最適當的溶劑系統下進行環氧壓克力樹脂/鎢錯合物混成材料的製作及性質分析。UV-Visible測試可了解材料的可見光透光性及抗近紅外光線等光學性質；以FT-IR檢測配位劑與鎢金屬配位過程中的官能基鍵結變化；利用SEM觀察混成材料微相結構，與鎢錯合物的混掺情形；TGA分析測試材料的熱穩定性。 由於WV及WVI混價會有吸收範圍紅移至近紅外光的現象，加入配位劑則有吸收度增強的效果。研究結果發現乙醇因氧化還原能力較強，且兼具配位基的角色，在WTBP系統中測試溶劑效應時對增幅效果相當顯著。因此本研究選用乙醇為溶劑。不同鎢錯合物吸收劑的近紅外光吸收效果依序為WTBP>WDEA>WEA>WAcAc>WDiPA>WEtOH。混成薄膜近紅外光吸收效果為WTBP>WEtOH>WAcAc>WDiPA>WEA>WDEA。以TBP為製作之混成材料具有大範圍、高強度近紅外光吸收，15wt.% WTBP吸收劑製作膜厚為20μm的吸收膜其近紅外光平均遮蔽率達85%，可見光平均穿透率為70%，具有優良的隔熱及透光性，深具近紅外光遮蔽薄膜應用的潛力。 In this research, synthesis and characterization of the UV curable expoxy acrylate/tungsten hybrid materials and their applications on the near infrared shielding film were investigated. The coordination ligands were incorporated to resolve the drawbacks of the NIR-shielding film nowadays such as poor and limited range of NIR absorption. The solvent effect was examined to choose the most suitable solvent system. Different coordination compounds were used to prepare the tungsten complex and the optical properties were carefully observed. The poly expoxy acrylate/tungsten optical films were prepared and charaterized. UV-visible spectrometer was used to evaluate the transmittance of the visible light and the NIR shielding ability of the polymeric film. FT-IR was used to investigate the evolution of chemical bonds between coordination ligands and tungsten. The morphology of organic/inorganic materials was observed by FESEM. The degradation temperature was measured by TGA. The mixed valence state of WV-WVI was the reason for the red shift phenomenon of the absorption range of light from visible to near infrared. The incorporation of coordination compound would enhance the NIR-shielding ability. The experimental results showed that the NIR-shielding ability decreased in the order of WTBP>WDEA>WEA>WAcAc>WDiPA>WEtOH. Ethanol was a better reducing agent to convert WVI to WV, and it is also a good solvent for the hybrid system. Hence, the test result of solvent effect indicated that ethanol was the most suitable solvent. The shielding performance of the polymer films decreased in the order of WTBP> WEtOH> WAcAc>WDiPA>WEA>WDEA. The TBP coordinated films have higher and broader NIR absorption observed in the experimental results. With 20μm film thickness and tungsten complex 15wt.% in epoxy-acrylate, 85% near-infrared light can be cut off and the transmittance of the visible light is over 70 %. The WTBP organic/inorganic material had excellent potential in near infrared shielding applications.
