The strive for utilization of green fillers in polymer composite has increased focus on application of natural biomass-based fillers. Biochar has garnered a lot of attention as a filler material and has the potential to replace conventionally used inorganic mineral fillers. Biochar is a carbon rich product obtained from thermochemical conversion of biomass in nitrogen environment. In this review, current studies dealing with incorporation of biochar in polymer matrices as a reinforcement and conductive filler were addressed. Each study mentioned here is nuanced, while addressing the same goal of utilization of biochar as a filler. In this review paper, an in-depth analysis of biochar and its structure is presented. The paper explored the various methods employed in fabrication of the biocomposites. A thorough review on the effect of addition of biochar on the overall composite properties showed immense promise in improving the overall composite properties. An analysis of the possible knowledge gaps was also done, and improvements were suggested. Through this study we tried to present the status of application of biochar as a filler material and its potential future applications.
在聚合物复合材料中使用绿色填料的努力使得人们更加关注基于天然生物质的填料的应用。生物炭作为一种填料材料受到了广泛关注，并且有潜力取代传统使用的无机矿物填料。生物炭是在氮气环境中通过生物质的热化学转化获得的富含碳的产物。在这篇综述中，探讨了当前关于将生物炭作为增强剂和导电填料掺入聚合物基体的研究。这里提到的每项研究都有细微差别，同时都致力于实现将生物炭用作填料这一相同目标。在这篇综述论文中，对生物炭及其结构进行了深入分析。本文探讨了制备生物复合材料所采用的各种方法。对添加生物炭对复合材料整体性能的影响进行的全面综述表明，在改善复合材料整体性能方面具有巨大潜力。还对可能存在的知识空白进行了分析，并提出了改进建议。通过这项研究，我们试图呈现生物炭作为填料材料的应用现状及其未来潜在应用。
