Following the leap forward in technology since the Industrial revolution population growth accelerates the demand for freshwater. For this background, there has been a growing body of research that explores the desalination for 97% of the seawater on earth. However, the prior art is an energy-intensive industry that uses fossil fuels as an energy source, which increases greenhouse gas emissions and the depletion of fossil fuels. it is contrary to the current trend to realize carbon neutrality. In this study, an ionic polymer-based membrane was used for eco-friendly desalination using solar heat. The material has a hydration characteristic that interacts with the ion by charging itself and has salt resistance. After that, a functional photothermal material was introduced into the ionic polymer to improve photo-thermal efficiency. The prepared membrane was evaluated through a thermal localization test and a solar steam generation test. |
