The continuous delivery of E-waste from petroleum-based products creates ecological and environmental problems due to non-biodegradable polymers, which release harmful chemicals and toxic gases. This results in biodegradable polymers/fibers appearance, which are biocompatible and degrade in the surrounding environments without causing any environmental pollution and these relieve environmental burden. However, the bio-based materials are unable to meet certain properties in the way of flexibility, dielectric properties, electrical properties, water and gas vapor barrier properties. The current day's research focus is towards the implementation of biodegradable composites properties by introducing different nanostructures. The biopolymers/biofibers are used as raw material in concern with environmental aspects. Nowadays researchers are supplementing a new form of materials known as nanofillers in various biopolymer-based composites in a small amount. This nanofillers will act as additives and helps in enhancing the different properties such as mechanical, thermal, flame retardancy and water absorption behavior of the nano composite materials as well as maintaining the optimum density of them. The nanocomposites applications are extended in various sectors for the reason of higher surface area, aspect ratio, and superior properties. This review outlines the types of biofibers/biopolymers and their characterization, types of nanofillers, and their characterization, and summarizes the various functional properties of nanocomposites with their applications.

纳米填料对生物可降解复合材料的影响：综合综述

由于不可生物降解的聚合物会释放有害化学物质和有毒气体，因此从石油产品中持续输送电子垃圾会造成生态和环境问题。这导致了可生物降解的聚合物/纤维的外观，它们具有生物相容性，可在周围环境中降解，不会造成任何环境污染，从而减轻环境负担。然而，生物基材料在柔韧性、介电性能、电性能、水和气体蒸汽阻隔性能方面无法满足某些性能。目前的研究重点是通过引入不同的纳米结构来实现可生物降解复合材料的特性。生物聚合物/生物纤维被用作与环境方面有关的原材料。如今，研究人员正在少量地在各种基于生物聚合物的复合材料中补充一种新形式的材料，称为纳米填料。这种纳米填料将起到添加剂的作用，有助于增强纳米复合材料的不同性能，如机械、热、阻燃和吸水行为，并保持它们的最佳密度。由于具有更高的表面积、纵横比和优异的性能，纳米复合材料的应用扩展到各个领域。本综述概述了生物纤维/生物聚合物的类型及其表征、纳米填料的类型及其表征，并总结了纳米复合材料的各种功能特性及其应用。
