随着柔性电子器件的发展，对价格低廉、环境友好的基板的要求越来越高。纤维素纸因其丰富性、可生物降解性和可再生性而备受关注。本文将天然纤维素纳米纤维(CNF)引入到纤维素纳米晶须(CNWs)基质中，设计了一种杂化纳米纸，在偏振膜下保持虹彩的同时，获得了较高的光学透过率。这种纳米纸比纯CNFS基纳米纸更便宜，更适合大规模生产。此外，我们的透明混合纳米纸具有像普通纸一样的可写表面。然而，与商用纸相比，杂化纳米纸表现出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基板的极佳候选者。(C)2014爱思唯尔有限公司。保留所有权利。
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. (C) 2014 Elsevier Ltd. All rights reserved.
