Analysis and application of nano cellulose eco-friendly materials in green buildings

Green building is a building concept that pursues environmental protection, resource conservation, and sustainable development, and the selection of materials has an important impact on building performance. This study proposes using nano cellulose–based materials in green buildings. Nano cellulose is utilised to prepare gel electrolytes for energy storage in photovoltaic systems. The performance analysis system of the material is constructed from many aspects, and the corresponding parameter calculation method is designed. The results demonstrated that the surface of the nano cellulose material was smoother and more flat in the 5 nm image by scanning electron microscopy. In the Raman spectroscopy test, the ratio of strong and weak hydrogen bond between molecules of the water energy storage material prepared by the research method was 0.62. In the nucleation over-potential test, the flexible energy storage material made by the research method reached the equilibrium potential at the position of −27.9 mV. In the charge–discharge curve test, the flexible energy storage material made by the research method had a capacitance of 45.3 F/g when the current density was 10 A/g. The results indicate that the environmental protection materials made by the research method have good material properties and energy storage capacity.
