The seawater desalination technology plays an important role in solving the problem of water shortage. In particular, the research of solar seawater technology has attracted more research and industry attentions. As an advanced and convenient processing method, laser micro/nano-manufacturing technology has made some achievements in the field of preparing seawater desalination materials in recent years. Based on the solar desalination and laser processing technologies as the research background, according to diverse research materials, we summarize the research progress of laser micro/nano-manufacturing technology in the preparation of seawater desalination materials from three different aspects, including carbon-based, metal-based and composite materials. Finally, challenges and prospects of this field are provided.
