碳纖維具有高強度、高耐熱性、優良導電性、低膨脹係數及低密度等優點;而石墨烯有高機械強度、高光穿透性、良好熱傳導以及高導電性等優點,使其成為近幾年來的研究熱點。本研究以碳纖維為核材料,先以原位聚合法製備聚苯胺/還原氧化石墨烯複合材料後,再將其包覆在碳纖維上形成聚苯胺/還原氧化石墨烯包覆碳纖維複合材料,探討改變還原氧化石墨烯之添加量的特性差異,並以FTIR、FE-SEM、UV-Vis、XRD、TGA、及四點探針儀進行檢測。
FTIR結果顯示複合材料皆具有聚苯胺官能基結構存在;SEM結果證實聚苯胺/石墨烯確實包覆在碳纖維表面;UV-Vis結果顯示複合材料中皆有聚苯胺的兩個特性波峰,在440nm附近主要是經鹽酸摻雜而造成質子化亞胺基所形成的特性吸收峰,在614nm附近主要是聚苯胺中醌環π-π*電子躍遷所造成;XRD結果顯示複合材料皆具有聚苯胺的兩個特性波峰,同時在2θ=13o出現特性波峰,主要是石墨烯與碳纖維所產生的氧化石墨相特性波峰;TGA結果顯示複合材料與純的聚苯胺相比,由於添加石墨烯及碳纖維,熱穩定性明顯增加;導電度分析結果顯示,聚苯胺/石墨烯包覆碳纖維複合材料中,當石墨烯含量為3wt%時,導電度可達107.02 S/cm。

Carbon fibers have the advantages of high strength, high heat resistance, excellent electrical conductivity, low expansion coefficient and low density. Furthermore, graphene has the advantages of high mechanical strength, high light transmittance, good thermal conductivity and high electrical conductivity, that make it become research hot spots. In this study, we use Carbon fibers as the core material, polyaniline/reduction graphene oxide composite material was prepared by in situ polymerization method, and then coated on the Carbon fibers to form a polyaniline/reduced graphene oxide coated Carbon fibers composite material, discuss the difference in the amount of graphene oxide and detected by FTIR, FE-SEM, UV-Vis, XRD, TGA, and four-point probe.
The FTIR results showed that all the composites have the polyaniline functional group structure. The SEM results can confirm that the polyaniline/graphene coating on the surface of the carbon fiber. The UV-Vis results showed that the composite material has two characteristic peaks of polyaniline. Around 440nm, the characteristic absorption peak mainly caused by hydrochloric acid doped protonated amino groups. Around 614nm, the characteristic absorption peak mainly caused by polyaniline quinoid ring π-π* electronic transition. The XRD results showed that all the composite materials have two characteristic peaks of polyaniline. The characteristic peaks appear at 2θ = 13o, which is the graphite oxide absorption peak caused by the graphite oxide and carbon fiber. The TGA results showed that, due to the addition of graphene and carbon fiber, the thermal stability of the composites was significantly higher than that of pure polyaniline. The conductivity analysis showed that the polyaniline/graphene coated Carbon fibers composite materials, when the dosage of graphene was 3wt%, the conductivity of up to 107.02 S/cm.
