Abstract

The need for achieving sustainable technologies has encouraged research on renewable and biodegradable materials for novel products that are clean, green, and environmentally friendly. Nanocellulose (NC) has many attractive properties such as high mechanical strength and flexibility, large specific surface area, in addition to possessing good wet stability and resistance to tough chemical environments. NC has also been shown to easily integrate with other materials to form composites. By combining it with conductive and electroactive materials, many of the advantageous properties of NC can be transferred to the resulting composites. Conductive polymers, in particular poly(3,4-ethylenedioxythiophene:poly(styrene sulfonate) (PEDOT:PSS), have been successfully combined with cellulose derivatives where suspensions of NC particles and colloids of PEDOT:PSS are made to interact at a molecular level. Alternatively, different polymerization techniques have been used to coat the cellulose fibrils. When processed in liquid form, the resulting mixture can be used as a conductive ink. This review outlines the preparation of NC/PEDOT:PSS composites and their fabrication in the form of electronic nanopapers, filaments, and conductive aerogels. We also discuss the molecular interaction between NC and PEDOT:PSS and the factors that affect the bonding properties. Finally, we address their potential applications in energy storage and harvesting, sensors, actuators, and bioelectronics.

摘要

实现可持续技术的需要鼓励了对可再生和可生物降解材料的研究，以生产清洁、绿色和环保的新型产品。纳米纤维素 (NC) 具有许多吸引人的特性，例如高机械强度和柔韧性、大比表面积，此外还具有良好的湿稳定性和对恶劣化学环境的耐受性。NC 还被证明可以轻松地与其他材料结合形成复合材料。通过将其与导电和电活性材料结合，NC 的许多有利特性可以转移到所得复合材料中。导电聚合物，特别是聚（3,4-乙烯二氧噻吩：聚（苯乙烯磺酸盐）（PEDOT：PSS），已成功与纤维素衍生物结合，其中 NC 颗粒悬浮液和 PEDOT 胶体：PSS 可以在分子水平上相互作用。或者，已使用不同的聚合技术来涂覆纤维素原纤维。当以液体形式加工时，所得混合物可用作导电油墨。本综述概述了 NC/PEDOT:PSS 复合材料的制备及其以电子纳米纸、细丝和导电气凝胶形式的制造。我们还讨论了 NC 和 PEDOT:PSS 之间的分子相互作用以及影响键合性能的因素。最后，我们讨论了它们在能量存储和收集、传感器、执行器和生物电子学中的潜在应用。本综述概述了 NC/PEDOT:PSS 复合材料的制备及其以电子纳米纸、细丝和导电气凝胶形式的制造。我们还讨论了 NC 和 PEDOT:PSS 之间的分子相互作用以及影响键合性能的因素。最后，我们讨论了它们在能量存储和收集、传感器、执行器和生物电子学中的潜在应用。本综述概述了 NC/PEDOT:PSS 复合材料的制备及其以电子纳米纸、细丝和导电气凝胶形式的制造。我们还讨论了 NC 和 PEDOT:PSS 之间的分子相互作用以及影响键合性能的因素。最后，我们讨论了它们在能量存储和收集、传感器、执行器和生物电子学中的潜在应用。
