近年來，能源短缺已成為全球面臨的重大問題，為了有效減緩地球環境的破壞，開發可再生能源已是當務之急。基於可再生能源的發電，滲透能源的能量轉換引起人們極大的興趣。本文聚焦於氧化石墨烯(GO)和聚電解質複合材料的開發，探討其在滲透能源領域的應用潛力。值得注意的是聚苯乙烯磺酸(PSS)的主鏈結構，有助於形成更好的離子選擇性通道及能量輸出，在層通道中，電解質的流動與帶負電的GO-PSS結構介面處與電雙層(EDL)交疊綜合作用下，反向離子(即Na+)即容易被吸引製薄膜的層間距上，從而形成電壓即電流。進而使氧化石墨烯薄膜提升達70 % 的功率密度，並在高濃度條件下實現較高的能源轉換效率。也藉由數值模擬與實驗研究了PSS的重量百分比對複合薄膜性能貢獻，透過添加聚電解質成功增加GO通道內的電荷密度，揭示了奈米通道內電荷分佈對滲透能源的重要影響，為GO-PSS複合材料廣泛應用前景提供了有力支持。此研究結果為開發可持續能源和解決能源問題提供新的可能性。

In recent years, the global energy shortage has emerged as a paramount concern, prompting the urgent need to develop renewable energy sources to mitigate environmental degradation effectively. This paper explores graphene oxide (GO) and polyelectrolyte composites, focusing on their potential applications in osmotic energy. The study emphasizes the importance of the main chain structure of polystyrene sulfonic acid (PSS) in facilitating the generation of enhanced ion selective channels and augmenting energy output. Within the nanochannel, an overlapped electrical double layer (EDL) at the interface between the electrolyte and the negatively charged GO-PSS structural interface at the electric double layer (EDL), and the counter ions (i.e., Na+) are readily attracted to the interlayer spacing of the membranes, resulting in the formation of voltages and currents. This leads to a notable 70% enhancement in the power density of graphene oxide membranes and achieving elevated energy conversion efficiency under high concentration conditions. Numerical simulations and experimental studies have been conducted to examine the influence of the PSS mass ratio on composite membranes' properties. The successful incorporation of polyelectrolytes has significantly increased the charge density within GO channels, unveiling the pivotal impact of charge distribution on osmotic energy. This research robustly supports the extensive utilization prospects of composite GO-PSS membranes. The conclusions drawn from this study provide innovative avenues for advancing sustainable energy development and effectively tackling energy-related challenges.
