Polypropylene (PP) nanocomposites were prepared using bottom-up graphene oxide (BGO) functionalized with cardanol having a long alkyl group as a filler. BGO was prepared from citric acid and tannic acid, and then further functionalized with cardanol glycidyl ether (CGE), where CGE was synthesized by reacting cardanol with epichlorohydrin to produce cardanol functionalized BGO (CBGO). PP nanocomposites were fabricated by mixing PP and CBGO using twin-screw extruder, where the content of CBGO ranged from 0.5 to 5.0 wt%. PP nanocomposite containing 2.0 wt% of CBGO (PP/CBGO-2.0) showed the maximum mechanical properties. The effect of the alkyl group in CBGO on the mechanical properties was investigated by comparing the mechanical properties of PP/CBGO-2.0 with those of PP nanocomposite with 2.0 wt% BGO (PP/BGO-2.0). For example, the tensile strength and Young’s modulus of PP/CBGO-2.0 increased by 20.1% and 30.6%, respectively, compared to neat PP, while those of PP/BGO-2.0 increased by 14.7% and 25.0%, respectively.

聚丙烯 (PP) 纳米复合材料是使用自下而上的氧化石墨烯 (BGO) 制备的，该氧化石墨烯 (BGO) 被具有长烷基的腰果酚作为填料。BGO 由柠檬酸和单宁酸制备，然后用腰果酚缩水甘油醚 (CGE) 进一步官能化，其中 CGE 是通过腰果酚与环氧氯丙烷反应生成腰果酚官能化 BGO (CBGO) 合成的。通过使用双螺杆挤出机将 PP 和 CBGO 混合来制备 PP 纳米复合材料，其中 CBGO 的含量范围为 0.5 至 5.0 wt%。含有 2.0 wt% CBGO (PP/CBGO-2.0) 的 PP 纳米复合材料表现出最大的机械性能。通过比较 PP/CBGO-2.0 的机械性能与含有 2.0 wt% BGO 的 PP 纳米复合材料 (PP/BGO-2.0) 的机械性能，研究了 CBGO 中烷基对机械性能的影响。例如，
