近年來人類對於能源的需求日益增加以及環保意識的著重，人們在追求能源的同時也重視可循環且潔淨的替代方案。潔淨的可再生綠色能源中主要有太陽能、風能與水能，其中以水資源是最穩定的。蒸發作用是環境循環中的一部份，為無時無刻都在進行的過程，因此是一種具有潛力的發電方式。在本研究中將以不織布浸塗碳黑的方式製作蒸發發電裝置，透過外在因素或內在因素使裝置內產生不同的體積流率來探討發電。吾等發現經氧電漿處理後的裝置可以使發電量增強，最佳的氧電漿處理時間約控制在三至五分鐘，且其效果性可延續一周以上。此外，透過改變浸塗碳黑的參數，吾等發現碳黑與介面活性劑的比例以及濃度對裝置的影響。最後透過控制環境濕度的實驗表明裝置的蒸發速率會受到濕度影響，不過對於濕度對於發電的效果影響不大，可以在一般環境條件下正常運作。含有鹽類的溶液同時也含有更多的離子，可以有效地增加裝置的效能。同時我們也成功使用並聯2組含有8組串聯的裝置點亮LED。藉由本研究能夠了解如何改善裝置的效能，並為開發高效能的裝置提供有用的訊息。

In this study, a non-woven fabric coated with carbon black will be used to produce an evaporative power generation device, which will generate electricity by capillary evaporation-driven water flow. In order to understand how to improve the performance of the device, we tried to use oxygen plasma treatment and change the parameter of carbon black. The results showed that the oxygen plasma treated device could enhance the power generation performance. The best oxygen plasma treatment time is about three to five minutes, and its duration of effect can be more than a week. It was also can see that the ratio between carbon black and surfactant would affect the performance of the device. Experiments with controlled ambient humidity show that the evaporation rate of the device is affected by humidity. However, the effect of humidity on power generation is not significant, and it can operate normally under normal environmental conditions. The solution containing salts also contains more ions, which can effectively increase the performance of the device. We have also successfully used two parallel groups of 8 series-connected devices to light up the LED. This study provides methods to improve the performance of the device and provides useful information for the development of high-performance devices.
