廢紙容器回收紙漿高值化應用-奈米纖維素產製技術開發
| 中文摘要 | 雖然台灣已逐步建立紙容器回收處理體系，但因仍面臨紙容器處理困難、回收再製紙漿等產品價值低、回收成本高等問題，並無法提升國內廠商投入紙容器回收產業的意願。若能以回收紙漿進行兼具優異物性及環保的奈米纖維素生產，即可透過高值化再生技術以提升資源利用價值。本計畫針對不同分類及來源之廢紙容器的再製紙漿進行組成與特性分析，結果顯示上述之紙漿在組成分析上都略有不同，但在本質之熱性質、結晶性等特性並無顯著差異。而在奈米纖維素製程技術開發上，本計畫利用氯化金屬鹽離子溶液進行纖維素的解纖維化處理，並透過組成、反應溫度以及反應時間等製程參數的調控，以進行奈米纖維素的製備。在特定處理條件下，不同來源之回收紙漿纖維都能順利完成奈米纖維素之製備，所得的奈米纖維素直徑約為30-50 nm，且整體產率能穩定達到80-90%。後續透過改質程序調控奈米纖維素之極性，以提高產物與高分子複合時的相容性，整體改質比例可藉由改質劑結構與改質比例進行調控。初步機械補強特性驗證上，奈米纖維素與高密度聚乙烯高分子材料所混練製成之複合材料，其楊氏模數可提升≥30%。 | ||

High Value-added Application of Recycle Pulps from Waste Paper Containers – Production of Nano Cellulose
| 英文摘要 | Even though a feasible treatment process of waste food containers has been established, only a low recycling rate of paper containers was fulfilled till now due to the severe contamination issues and difficulties in separation processes. In addition, low economic value of regenerated products along with high recycling costs also limit its development. High value-added nano celluloses, with merits of superior mechianical properties and environmental benign, could provide a possibility for paper circular economy. The composition analyses of the recycled pulps were conducted in this project. Although the compositions of different pulps are varied, the physical properties, including crystallinity and thermal stability, are similar. In addition, the manufacturing process of nano cellulose from pulps was established. Metallic chloride salts-based ionic solutions were adopted to produce nano cellulose. The effects of composition, reaction temperature and time on cellulose defibrillation has been evaluated. Under the optimized reaction paramaters, the pulp cellulose could form cellulose nanofibers homogeneously, of which the diameters ranging from 30-50 nm. The yield of nano cellulose could reach 80-90% due to a mild reaction in nature. The surface polarity of nano cellulose was adjusted via modification to enhance the compatibility with polymers. The evaluation of reinforcement effect of nano cellulose was conducted by compounding with different polymers. The nano cellulose/HDPE composite shows an increasement of Young’s modulus over 30%. | ||
