Nanodelamination and controlled stripping of two-dimensional materials are important ways to realize the release of the performance of nano-functional materials. This work shows that hydroquinone (HQ) intercalated nickel-cobalt hydroxides (NiCoLDHs) have been nanodelaminated in different solvents (water, ethanol, ethanol/water, and toluene) and physical treatment (ultrasonic bath, magnetic stirring, and hydrothermal). Scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffraction techniques (XRD), Fourier transform infrared (FT-IR), thermal analyses (DSC-TGA), and Brunauer-Emmett-Teller (BET) were used to characterize the structures of all the samples. The results show that nanodelamination of the treated NiCoLDHs-HQ samples with three kinds of physical treatment in different solvents reduces the intensity of the characteristic d₀₀₁ reflections and moves to the smaller angle, indicating that the HQ is an effective nanodelamination intercalation agent. Microstructure and BET analysis also demonstrate that NiCoLDHs achieve high-efficiency nanodelamination driven by HQ in ethanol and ultrasonic bath than that of other in solvents and physical treatment. This significant delamination effect is mainly attributed to the interaction between hydroquinone and NiCoLDHs or solvent, and this delamination strategy provides a new method for efficient application of 2D material as electrode, catalyst, or polymer/clay nanocomposites.

二维材料的纳米分层和受控剥离是实现释放纳米功能材料性能的重要方法。这项工作表明对苯二酚（HQ）插层的镍钴氢氧化物（NiCoLDHs）已在不同的溶剂（水，乙醇，乙醇/水和甲苯）和物理处理（超声波浴，磁力搅拌和水热法）中进行了纳米分层。扫描电子显微镜（SEM），透射电子显微镜（TEM），X射线衍射技术（XRD），傅立叶变换红外（FT-IR），热分析（DSC-TGA）和Brunauer-Emmett-Teller（BET）用于表征所有样品的结构。d ₀₀₁反射并移动到较小的角度，表明HQ是有效的纳米分层插入剂。微观结构和BET分析还表明，NiCoLDHs在乙醇和超声浴中由HQ驱动，比在溶剂和物理处理中实现了更高的纳米分层。这种明显的分层效果主要归因于氢醌与NiCoLDHs或溶剂之间的相互作用，并且这种分层策略为有效地将2D材料用作电极，催化剂或聚合物/粘土纳米复合材料提供了一种新方法。
