以廢甘油為基礎製備生物可分解高分子--材料，製程及產品開發

為響應對環保聚合物材料不斷增長的需求，我們提出了一種高效的微波系統來製造以甘油為基底的生物可降解高分子聚合物材料，以取代現有的聚合物。與傳統的紅外線加熱法相比，使用行波的連續微波乾燥設備能夠將聚合物合成時間從大約一天減少到10分鐘左右。此套系統結合捲對捲設備，有利於量產生物可降解薄膜（Biodegradable film）。以甘油和馬來酸為原料的PGM（poly glycerol maleate，聚馬來酸甘油酯）配方可以在水和土壤中快速分解。除了具有更好的生物降解性外，PGM還比其他可分解材料便宜，因此在市場競爭中具有優勢，且使用廢棄甘油可以減少回收處理之費用，亦是達成循環經濟的目標。我們將繼續優化材料配方，以發展它在各方面的應用，如生物可分解膠水、塑料等。此外我們也將繼續研究生物可降解性的機制，並使微波烘箱的結構輕量化，可以方便拆卸、清洗，將各種微波系統集成到量產規模，提高使用效率及產量。

In response to the increasing demand for environmental friendly polymeric materials, we propose an efficient microwave system to manufacture glycerol-based biodegradable polymeric materials in the hope of substituting existing polymers. The microwave-drying apparatus by using the quasi-travelling wave is capable of reducing the processing time from a day to 10 minutes compared with the traditional IR (infrared)-heating method. The roll-to-roll crosslink inside the system is beneficial to produce the biodegradable films. The new formulation of PGM (poly glycerol maleate) by using the glycerol and maleic acid as raw materials can be decomposed in water and soil rapidly. In addition to having better biodegradability, PGM is cheaper than other decomposable materials and therefore has an advantage in market competition. Finally, we will continue to optimize materials design, investigate the mechanism of biodegradability and integrate various subsystems to pilot scale.
