| 1 | Strong and Superhydrophobic Wood with Aligned Cellulose Nanofibers as a Waterproof Structural Material显示文摘Lightweight structural materials are important for the energy efficiency of applications,particularly those in the building sector.Here,inspired by nature,we developed a strong,superhydrophobic,yet lightweight material by simple in situ growth of nano-SiO2 and subsequent densification of the wood substrate.In situ generation of SiO2 nanoparticles both inside the wood channels and on the wood surfaces gives the material superhydrophobicity,with static and dynamic contact angles of 159.4°and 3°,respectively.Densification of the wood to remove most of the spaces among the lumen and cell walls results in a laminated,dense structure,with aligned cellulose nanofibers,which in turn contributes to a high mechanical strength up to 384.2 MPa(7-times higher than natural wood).Such treatment enables the strong and superhydrophobic wood(SH-Wood)to be stable and have excellent water,acid,and alkaline resistance.The high mechanical strength of SH-Wood combined with its excellent structural stability in harsh environments,as well its low density,positions the strong and superhydrophobic wood as a promising candidate for strong,lightweight,and durable structural materials that could potentially replace steel. | Yongfeng Li Chaoji Chen Jianwei Song Chunpeng Yang Yudi Kuang Azhar Vellore Emily Hitz Mingwei Zhu Feng Jiang Yonggang Yao Amy Gong Ashlie Martini Liangbing Hu | 2020 | Chinese Journal of Chemistry2020，38，8： | 1 |
