Abstract

The integration of broadband sound absorption with environmental sustainability remains a key challenge in advanced material design. In this work, an innovative 3D-printed cellulose nanofibril (CNF) architecture with a customizable hierarchical “hole-cavity unity” structure was proposed for highly efficient sound absorption. This multi-scale structural design strategy synergistically coupled the perforated-panel acoustic principles with nanoscale viscous dissipation mechanisms. By leveraging the shear-thinning behavior of CNF inks and the precision control of direct ink writing, the sub-millimeter periodic pore arrays were embedded within the continuous nanofibrous network, enabling programmable structural tunability across multiple pore scales. Systematic regulation of infill ratio and sample thickness yielded high sound absorption coefficients (>0.7) over an ultra-broad frequency range of 1.2–6.3 kHz. Combined with low shrinkage, structural customizability, low density, and rapid environmental degradability, the fully bio-based 3D-printed CNF architectures are expected to offer a promising and sustainable solution for developing next-generation acoustic materials for noise control applications.

3d打印可编程分层孔腔结构的全纤维素纳米纤维可调宽带吸声

将宽带吸声与环境可持续性相结合仍然是先进材料设计中的一个关键挑战。在这项工作中，提出了一种创新的3d打印纤维素纳米纤维（CNF）结构，具有可定制的分层“孔腔统一”结构，用于高效吸声。这种多尺度结构设计策略协同耦合了穿孔板声学原理和纳米尺度粘性耗散机制。通过利用CNF油墨的剪切变薄行为和直接墨水写入的精确控制，亚毫米周期孔隙阵列被嵌入到连续的纳米纤维网络中，实现了跨多个孔隙尺度的可编程结构可调性。在1.2-6.3 kHz的超宽频率范围内，系统调节填充比和样品厚度可获得高吸声系数（>0.7）。结合低收缩率、结构可定制性、低密度和快速的环境降解性，全生物基3d打印CNF结构有望为开发用于噪声控制应用的下一代声学材料提供有前途和可持续的解决方案。

期刊介绍： Carbohydrate Polymers stands as a prominent journal in the glycoscience field, dedicated to exploring and harnessing the potential of polysaccharides with applications spanning bioenergy, bioplastics, biomaterials, biorefining, chemistry, drug delivery, food, health, nanotechnology, packaging, paper, pharmaceuticals, medicine, oil recovery, textiles, tissue engineering, wood, and various aspects of glycoscience. The journal emphasizes the central role of well-characterized carbohydrate polymers, highlighting their significance as the primary focus rather than a peripheral topic. Each paper must prominently feature at least one named carbohydrate polymer, evident in both citation and title, with a commitment to innovative research that advances scientific knowledge.
