Functional Bio-nanocomposites: Chemi-mechanical and Morphological Attributes

纤维素纳米和微纤丝的分离和应用在各种研究和先进技术应用中迅速扩大，由于它们的环境效益和特定的功能特性，特别是在纳米材料科学中。据报道，天然形式的纤维素的拉伸弹性模量沿链轴沿着高达138 GPa。尽管许多文献强调了在结构组分中使用微米和纳米纤维素作为强度增强剂的潜力，但没有实际证据证明纳米纤维素作为特别强度增强剂的作用。为了赋予复合材料中纳米纤维素的强度特性，需要更好地理解纳米纤维素及其衍生自化学和生物过程的衍生物的物理化学、结构和形态学特性。 拟议的研究的目的是克服障碍，通过了解基于纤维素原纤维的复合材料的表面，内在和形态特征的纤维的性能的依赖性，应用纳米纤维素的独特特性。纤维素与其他分子的纤维表面结合性能的影响，纤维形态和微观结构上的transmittance，因此界面，如果理解，可以用来开发/纳米纤维增强可回收的纳米复合材料具有独特的功能和性能特性。

Isolation and application of cellulose nano and microfibrils in various research and advanced technological applications are expanding rapidly due to their environmental benefits and specific functional properties, especially in nanomaterial science. The tensile modulus of elasticity of native forms of cellulose has been reported to be as high as 138 GPa along the chain axis. Although numerous literatures highlighted potential to use micro-and nano-cellulose in structural components as strength enhancer, no practical evidence is available to demonstrate the role of nanocellulose as an extra-ordinary strength enhancer. In order to impart the strength characteristics of nanocellulose in a composite material there is a need to better understand the physico-chemical, structural and morphological characteristics of nanocellulose and its derivatives derived from chemical and biological processes. The aim of the proposed research is to overcome barrier to apply unique characteristics of nanocellulose by understanding the dependence of cellulosic fibrils-based composites properties on surface ,intrinsic and morphological characteristics of the fibres. The effect of fiber surface binding properties of cellulose with other molecules, fibre morphology and microstructure on transcrystallinity, and hence the interface, if understood, could be used to develop /nano fibre reinforced recyclable nanocomposites with unique functional and performance properties.
