Cellulose microfibers were successfully fabricated from Vietnamese Nipa palm by mechanical and chemical treatments. The Nipa palm petioles were simply rolled, pressed, and separated. They were then pretreated with an alkaline solution and submitted to acid hydrolysis to remove the impurities (tCell). The microfibers were reinforced with reduced graphene oxide to form a hybrid that was reduced with hydrazine hydrate in the last stage (tCell-rGO). The structure and properties of tCell and tCell-rGO were evaluated by FTIR, XRD, DSC, TGA, SEM, BET, and the sheet resistance. It was observed that the treated cellulose microfibers exhibited a diameter of 10–20 μm and had good crystallinity in the structure. Both tCell and tCell-rGO exhibited low-density values of 1.52 kg/m³ and 0.58 kg/m³, respectively, and had good specific surface area values of 11.2 m²/g and 13.0 m²/g, respectively. These results supported the decrease in the density and the increase in the specific surface area of the tCell-rGO samples in comparison with the tCell. The existence of rGO sheets in the cellulose microfiber matrix resulted in changes in the structure, arrangement, and crystallization of pristine microfibers. The thermal property and electrical conductivity of the reinforced GO cellulose microfibers were significantly improved. rGO not only showed its role as a surface modification agent that helps the cellulose microfibers disperse better in the non-polar substrate, but also contributed to the increase of the heat-stable and mechanical properties of polymer. The thermal stability of tCell-rGO/PMMA composite was notably improved more than 40°C in maximum decomposition temperature by an emulsion polymerization technique. The material based on cellulose microfibers from the Vietnamese Nipa palm tree and reduced graphene oxide overcame some disadvantages such as the poor heat resistance, poor dispersion of the original fibers in the non-polar polymer and displayed great potential for environmentally friendly future applications.

纤维素超细纤维是通过机械和化学处理成功地由越南尼帕棕榈制成的。将尼帕棕榈叶柄简单地滚动，压紧并分开。然后用碱性溶液对其进行预处理，然后进行酸水解以除去杂质（tCell）。用还原的氧化石墨烯增强微纤维，形成杂化物，最后阶段用水合肼还原（tCell-rGO）。通过FTIR，XRD，DSC，TGA，SEM，BET和薄层电阻来评估tCell和tCell-rGO的结构和性质。观察到，处理过的纤维素微纤维的直径为10–20μm，并且在结构中具有良好的结晶度。tCell和tCell-rGO都显示出1.52 kg / m ³和0.58 kg / m ³的低密度值分别具有11.2 m ² / g和13.0 m ^2的良好比表面积/ g。这些结果支持与tCell相比tCell-rGO样品的密度降低和比表面积的增加。纤维素微纤维基质中rGO片的存在导致原始微纤维的结构，排列和结晶发生变化。增强型GO纤维素超细纤维的热性能和电导率得到了显着改善。rGO不仅显示出其作为表面改性剂的作用，有助于纤维素微纤维更好地分散在非极性基质中，而且还有助于提高聚合物的热稳定性和机械性能。通过乳液聚合技术，tCell-rGO / PMMA复合材料的热稳定性在最高分解温度下显着提高了40°C以上。
