摘　　要：海洋中蕴含着丰富的清洁可再生能源,海洋能源的开发利用将是后化石能源时代解决能源问题的根本途径之一.当前海洋能转化主要依赖于电磁发电机,但是它们的物理原理使其直接转化低频、无序海洋能源的效率很低.近年来新兴的摩擦纳米发电机(TENG)恰恰在低频、高熵能量收集上具有显著优势,提供了海洋能高效开发的一种颠覆性技术路径.自2014年利用TENG网络收集大范围海洋蓝色能源的思想被我们首次提出以来,国内外已在蓝色能源器件及其发电网络的结构与性能优化、能量管理技术、海洋环境的自驱动系统应用等方面取得很大的进展,已完成原理验证.然而,在蓝色能源技术的进一步迭代、海洋环境的工程应用开发上还需要进行持续的探索.本文首先阐述了基于纳米发电机的蓝色能源的原创思想与技术优势,接着概括了蓝色能源相关研究的整体进展,最后展望了海洋蓝色能源研究的发展趋势和挑战.Oceans contain abundant clean renewable energy,and the development and utilization of ocean energy will be a fundamental approach to solving the energy problem in the post-fossil energy era.Current ocean energy conversion mainly relies on electromagnetic generators,but their physical principle makes them inefficient for directly converting low-frequency and disordered ocean energy.By contrast,recently-emerging triboelectric nanogenerators(TENGs)exhibit significant advantages in low-frequency and high-entropy energy harvesting,which provide a subversive technical path for the efficient development of ocean energy.Since the idea of using TENG networks to harvest large-scale blue energy was first proposed by our team in 2014,great progress has been made in the structure and performance optimization of blue energy harvesting devices and networks,power management technologies,and self-powered system applications in marine environment.Now the principle verification has been completed.However,continuous explorations are required in terms of further iteration for blue energy technologies,and engineering application developments in marine environment.This paper provides a comprehensive review of the original idea of blue energy,technology advantages,and the overall process of the related research of blue energy,and discusses the perspectives and challenges for blue energy harvesting.
