Thermal and Optical Properties of a DAST-PU Guest-Host Polymer System

有機非線性材料DAST-PU高分子混摻系統之熱性質及光性質研究

摘要


本研究研製出具非線性光學性質(NLO)材料之DAST晶體。利用此晶體混摻入PU高分子中形成主客型高分子系統對其熱性質及光學性質進行探討。由熱分析結果顯示本主客型NLO高分子系統在溫度240℃時仍具熱穩定性。另由通訊系統中光損失特性之測試結果得知此系統在波長1310nm處光衰減量可由DAST晶體之4.83dB減低至2.53dB,1550nm處之光衰減量由晶體之3.85dB減低至1.80dB。顯示此型高分子材料具研製成低光損失,耐熱性良好潛力之光元件材料。

The DAST prepared in this study was used as a guest crystal to blend with a thermal stable PU polymer host to form a guest-host polymer system. The thermal properties and the optical property of the DAST thin film as well as the optical attenuation characteristics of the DAST-PU film were studied. The results showed that the guest-host polymer film was stable up to 240℃ and its optical loss was less than 2.53 dB at 1310 nm and 1.8 dB at 1550 nm, respectively.
