With the development of flexible electronic devices, there is increasing requirement for the inexpensive and environmental-friendly substrates. Cellulose paper has gained great attention because of its abundance, biodegradability and renewability. In this paper, we designed a hybrid nanopaper by introducing native cellulose nanofibrils (CNFs) into cellulose nanowhiskers (CNWs) matrix, which achieved a high optical transmittance while retaining iridescence under polarizing film. This nanopaper is less expensive than neat CNFs-based nanopaper and more feasible for large-scale production. Besides, our transparent hybrid nanopaper possesses the writable surface like regular paper. Compared with commercial paper, however, hybrid nanopaper shows superior optical properties and low surface roughness. The combination of these characteristics makes this nanopaper an excellent candidate for substrates of flexible electronic devices.
随着柔性电子设备的发展,人们对廉价、环保的衬底材料的需求日益增加。纤维素纸因其丰富、可生物降解和可再生的特点而受到广泛关注。在本文中,我们通过将天然纤维素纳米纤维(CNFs)引入纤维素纳米晶须(CNWs)基质中,设计了一种混合纳米纸,在偏光膜下保留了虹彩,同时实现了高透光率。与纯 CNFs 基纳米纸相比,这种纳米纸价格更低廉,更适合大规模生产。此外,我们的透明混合纳米纸具有类似于普通纸的可书写表面。然而,与商业用纸相比,混合纳米纸具有更好的光学性能和更低的表面粗糙度。这些特性的结合使这种纳米纸成为柔性电子设备衬底的理想选择。
