第五章 結論與建議
5.2 後續實驗建議
在本實驗中仍然有部分需要改進並且檢討，整理如下：
1. 在雷射熱壓實驗中由於雷射端到熱壓材料表面需要三次的反射，會 使雷射效果變弱，可以將雷射反射數盡可能減少，以確保雷射對於 熱壓成品的影響。
2. 對於熱壓成品結晶度的觀察，可以使用微熱差掃瞄卡計(Differential scanning calorimetry, DSC)來做計算，微熱差掃瞄卡計可以用於檢測 材料的結晶熱、玻璃轉換溫度、熔點等參數，其中相對結晶度可以 由吸熱與時間關係圖中計算出，這有助於觀察雷射照射對材料造成 的微小改變。
3. 對於球晶的觀察可以使用偏光顯微鏡或者穿透式電子顯微鏡，此外 在觀察球晶內部分子鏈的排列狀態，可以用傅立葉轉換紅外線光譜 儀(Fourier transform infrared spectroscopy, FTIR)來觀測，可以了解 材料在堆疊片晶時分子練旋轉的狀態。
4. 微結構內部由於散熱太快以致於無法得到高次構造，可以配合學長 開發的可自發熱模仁在熱壓時加熱，使微結構內部的熱量足夠讓分 子鏈排列成片晶或者球晶，藉此改善材料的性質。
