Cellulose nanomaterials (CNs) are promising green materials due to their unique properties as well as their environmental benefits. Among these materials, cellulose nanofibrils (CNFs) and nanocrystals (CNCs) are the most extensively researched types of CNs. While they share some fundamental properties like low density, biodegradability, biocompatibility, and low toxicity, they also possess unique differentiating characteristics such as morphology, rheology, aspect ratio, crystallinity, mechanical and optical properties. Therefore, numerous comparative studies have been conducted, and recently, various studies have reported the synergetic advantages resulting from combining CNF and CNC. In this review, we initiate by addressing the terminology used to describe combinations of these and other types of CNs, proposing "hybrid cellulose nanomaterials" (HCNs) as the standardized classifictation for these materials. Subsequently, we briefly cover aspects of properties-driven applications and the performance of CNs, from both an individual and comparative perspective. Next, we comprehensively examine the potential of HCN-based materials, highlighting their performance for various applications. In conclusion, HCNs have demonstraded remarkable success in diverse areas, such as food packaging, electronic devices, 3D printing, biomedical and other fields, resulting in materials with superior performance when compared to neat CNF or CNC. Therefore, HCNs exhibit great potential for the development of environmentally friendly materials with enhanced properties.
纤维素纳米材料（CNs）因其独特的性能以及环境效益而成为很有前景的绿色材料。在这些材料中，纤维素纳米纤维（CNFs）和纳米晶体（CNCs）是研究最为广泛的CNs类型。虽然它们具有一些基本特性，如低密度、生物可降解性、生物相容性和低毒性，但它们也具有独特的区别性特征，如形态、流变学、长径比、结晶度、机械和光学性能。因此，已经进行了大量的比较研究，最近，各种研究报告了将CNF和CNC结合所产生的协同优势。在本综述中，我们首先讨论用于描述这些和其他类型CNs组合的术语，提出“混合纤维素纳米材料”（HCNs）作为这些材料的标准化分类。随后，我们从个体和比较的角度简要介绍性能驱动的应用以及CNs的性能方面。接下来，我们全面研究基于HCN的材料的潜力，突出它们在各种应用中的性能。总之，HCNs在食品包装、电子设备、3D打印、生物医学和其他领域等不同领域都取得了显著成功，与纯CNF或CNC相比，得到了性能更优越的材料。因此，HCNs在开发具有增强性能的环保材料方面具有巨大潜力。
