Biocomposite materials have a significant function in saving the environment by replacing artificial plastic materials with natural substances. They have been enrolled in many applications, such as housing, automotive engine components, aerospace and military products, electronic and circuit board components, and oil and gas equipment. Therefore, continuous studies have been employed to improve their mechanical, thermal, physical properties. In this research, we conduct a comprehensive review about corn fiber and corn starch-based biocomposite. The results gained from previous studies were compared and discussed. Firstly, the chemical, thermal, and mechanical properties of cornstarch-based composite were discussed. Then, the effects of various types of plasticizers on the flexibility of the cornstarch-based composite were addressed. The effects of chemical treatments on the properties of biocomposite using different cross-linking agents were discussed. The corn fiber surface treatment to enhance interfacial adhesion between natural fiber and polymeric matrix also were addressed. Finally, morphological characterization, crystallinity degree, and measurement of vapor permeability, degradation, and uptake of water were discussed. The mechanical, thermal, and water resistance properties of corn starch and fibers-based biopolymers show a significant improvement through plasticizing, chemical treatment, grafting, and cross-linker agent procedures, which expands their potential applications.
生物复合材料通过用天然物质替代人造塑料材料，在保护环境方面具有重要作用。它们已被应用于许多领域，如住房、汽车发动机部件、航空航天和军事产品、电子和电路板部件以及石油和天然气设备。因此，人们一直在进行持续研究以改善其机械、热学和物理性能。在本研究中，我们对基于玉米纤维和玉米淀粉的生物复合材料进行了全面综述。对先前研究获得的结果进行了比较和讨论。首先，讨论了基于玉米淀粉的复合材料的化学、热学和机械性能。然后，探讨了各种类型的增塑剂对基于玉米淀粉的复合材料柔韧性的影响。讨论了使用不同交联剂的化学处理对生物复合材料性能的影响。还探讨了用于增强天然纤维与聚合物基体之间界面粘附力的玉米纤维表面处理。最后，讨论了形态表征、结晶度以及透气率、降解和吸水率的测量。通过增塑、化学处理、接枝和交联剂处理程序，基于玉米淀粉和纤维的生物聚合物的机械、热学和耐水性性能有了显著改善，这扩大了它们的潜在应用范围。
