Abstract

Cellulose nanocrystals (CNCs) with high specific surface area, crystallinity, aspect ratio with unique rod-like shapes, elastic modulus and tensile strength are an excellent additive which can be used for the preparation of unique polymer/nanoparticle fiber composites from polymer solutions by electrospinning. Research on electrospinning as a technique has grown rapidly since 1990 with the number of publications increasing exponentially after 2005. The sudden increase in academic interest after 2005 was due to the electrospinning of various numbers of nanoparticles for diverse applications, including CNCs from polymer solutions. Although there are many preparation options and potential applications for using CNCs in electrospinning, the role of processing variables and interfacial interactions between CNCs, solvents and polymers must be fully understood before the desired objectives can be achieved. Since one of the unique features of CNCs is their modifiable surface chemistry, there are promising outcomes when using CNCs by tailoring CNCs/solvent and CBCs/polymer interfaces. We present a discussion that helps to show the whole process, including variables, of using CNCs as an electrospinning additive nanoparticle. We also discuss the existing and potential applications with different set ups.

摘要

纤维素纳米晶体 (CNC) 具有高比表面积、结晶度、具有独特棒状形状的纵横比、弹性模量和拉伸强度，是一种极好的添加剂，可用于通过静电纺丝从聚合物溶液中制备独特的聚合物/纳米颗粒纤维复合材料. 自 1990 年以来，关于静电纺丝技术的研究发展迅速，2005 年之后出版物的数量呈指数增长。2005 年之后学术兴趣的突然增加是由于静电纺丝用于各种应用的各种数量的纳米颗粒，包括来自聚合物溶液的 CNC。尽管在静电纺丝中使用 CNC 有许多准备选项和潜在应用，但加工变量的作用和 CNC 之间的界面相互作用，在达到预期目标之前，必须充分了解溶剂和聚合物。由于 CNCs 的独特功能之一是其可修饰的表面化学性质，因此通过定制 CNCs/溶剂和 CBCs/聚合物界面来使用 CNCs 会产生有希望的结果。我们提出的讨论有助于展示使用 CNCs 作为静电纺丝添加剂纳米粒子的整个过程，包括变量。我们还讨论了具有不同设置的现有和潜在应用程序。使用 CNCs 作为静电纺丝添加剂纳米颗粒。我们还讨论了具有不同设置的现有和潜在应用程序。使用 CNCs 作为静电纺丝添加剂纳米颗粒。我们还讨论了具有不同设置的现有和潜在应用程序。
