Development of surface-engineering strategies, which are facile, versatile, and mild, are highly desirable in tailor-made functionalization of high-performance bioinspired nanocomposites. We herein disclose for the first time a general organocatalytic strategy for the functionalization and hydrophobization of nacre-mimetic nanocomposites, which includes vide supra key aspects of surface engineering. The merging of metal-free catalysis and the design of nacre-mimetic nanocomposite materials were demonstrated by the organocatalytic surface engineering of cellulose nanofibrils/clay nanocomposites providing the corresponding bioinspired nanocomposites with good mechanical properties, hydrophobicity, and useful thia-, amino, and olefinic functionalities.
开发简便、通用且温和的表面工程策略，对于高性能仿生纳米复合材料的定制功能化而言是非常必要的。我们在此首次公开了一种用于珍珠母仿生纳米复合材料功能化和疏水化的通用有机催化策略，其中包括上述表面工程的关键方面。通过纤维素纳米原纤/粘土纳米复合材料的有机催化表面工程，证明了无金属催化与珍珠母仿生纳米复合材料设计的融合，为相应的仿生纳米复合材料提供了良好的机械性能、疏水性以及有用的硫、氨基和烯烃官能团。
