| Abstract:With the global energy crisis and environmental problems becoming increasingly severe， the development of efficient， clean， and renewable energy technologies has become a top priority. By efficiently absorbing solar radiation and converting it into heat， photothermal conversion materials not only broaden the utilization dimension of solar energy， but also effectively reduce the dependence on traditional fossil energy. In recent years， lignin has received extensive attention in the field of photothermal conversion. As the largest aromatic organic polymer compound in nature， lignin has many unsaturated groups and conjugated structures， showing considerable potential for photothermal conversion， and has been explored in the fields of energy harvesting and storage， seawater desalination， and photothermal therapy. In this paper， the structure， photothermal conversion principle， and modification strategy of lignin were introduced， the preparation methods of different lignin-based photothermal materials and their application in the field of photothermal conversion were reviewed， and their future development was prospected， in order to provide reference for the development of new photothermal conversion materials. |
