全球的薄膜市場需求預計將以年率8.6%成長，並於2019年達到264億美元的市場產值。此快速成長的原因，緣自於各國政府部門對飲用水或放流水標準日趨嚴格，食品、飲料和醫藥品等主要產業的生產量增加及其對純度需求的提升等因素，皆促進了高品質薄膜分離技術的市場需求。 廢輪胎主要由天然橡膠、合成橡膠、碳黑、鋼絲及纖維所組成；其中所含的有價橡膠資源係合成薄膜材料的主要高分子原料之一。因此，本研究將開發再利用廢輪胎為薄膜之新穎合成技術。於計畫第一年，以熱壓法製備緻密型分離膜，並將其應用於氣體分離，如CO2/CH4、olefin/paraffin等領域。研究過程將探討相關製備參數，並進行FESEM、XRD等特性分析，以探討膜結構對分離效能之關係。 本計畫已獲得以熱壓法製備緻密型氣體分離膜的重要操作條件與氣體滲透-分離效率之關係。經以TGA、FT-IR及去交聯程度分析顯示，本次所使用之再生膠原料以NR及SBR成份為主，且以組成份中含碳量少、經脫硫處理的再生膠，較適用於熱壓法製膜。熱壓製膜時以不使用中間層鏤空模具方式，能有利於提升各氣體之滲透及分選效果。 此外，本研究也同時掌握了初步的重要的熱壓製程條件包括熱壓溫度、熱壓壓力、熱壓時間，其結果顯示：(1)當以不同熱壓溫度製膜時，會提供不同量及大小的自由體積。(2)熱壓壓力越大，使氣體通量增加。(3)熱壓時間延長，使得薄膜內高分子結構更加緊密、自由體積減少。 本研究成功開發一簡單的方式來製備緻密型氣體分離膜，此法不僅能簡化廢輪胎再利用之程序，開發新穎再利用管道，且由熱壓法所製的橡膠態高分子膜，其CO2/N2選擇率更可達12.8。

The global demand for membranes is expected to grow at an annual rate of 8.6 % and reach a market value of 26.4 billion U.S. dollars in 2019. The reason for this rapid growth stems from the fact that the government departments in various countries have established much strict standard in drinking water and discharge flow standards. The increase in production of major industries such as food, beverages and pharmaceuticals, and the increase in demand for purity have all contributed to the high quality Market demand for membrane separation technology. Waste tires are mainly composed of natural rubber, synthetic rubber, carbon black, steel wire and fiber; the valuable rubber resources contained therein are one of the main polymer raw materials for synthesis of membrane. Therefore, this research will develop a novel synthesis technology for reusing waste tires as a membrane material. In the first year of the project, a dense separation membrane was prepared by hot pressing process and applied to gas separation such as CO2 / CH4, olefin / paraffin and other fields. This study has evaluated the relevant preparation parameters, and FESEM, XRD and other characteristics analysis were used to analyzed the membrane structure of the relationship between the separation efficiency. This project has obtained the relationship between the important operating conditions for the dense gas separation membrane prepared by hot pressing and the gas perm-selectivity performance. The TGA, FT-IR and de-crosslinking degree analysis indicated that the reclaimed rubber used in this study is mainly composed of NR and SBR, which have less carbon content and low crosslinking degree is more usable for membrane fabrication. The dense membrane prepared without using module shows the high perm-selectivity simultaneously.
