“…Consequently, the oxyfluorinated carbon fibers have a higher peak intensity than that of the as-received carbon fibers, especially the intensity of the carbon-fluorine group of fibers. This result can affect the surface characteristics of the fibers, resulting in oxyfluorination of carbon fibers is largely used to improve their adhesive properties and/or wettability between the fibers and the matrix due to the increase in specific polarity and the formation of O x -F x bonding of the oxyfluorinated carbon fiber surfaces [30,31].

In this work, the effects of maleic anhydride (MA) content on mechanical properties of chopped carbon fibers (CFs)-reinforced MA-grafted-polypropylene (MAPP) matrix composites. A direct oxyfluorination on CF surfaces was applied to increase the interfacial strength between the CFs and MAPP matrix. The mechanical properties of the CFs/MAPP composites are likely to be different in terms of MA content. Surface characteristics were observed by scanning electron microscope, Fourier transform infrared spectroscopy, and single fiber contact angle method. The mechanical properties of the composites were also measured by a critical stress intensity factor (K IC ). From the K IC test results, the K IC values were increased to a maximum value of 3.4 MPa with the 0.1 % of MA in the PP, and then decreased with higher MA content.

“…In the case of MWCNT, C 1s and O 1s peaks were observed. The C 1s peak was observed by graphitic carbon structure in MWCNT [30]. The O 1s peak was probably observed due to the generated chemical bonds between carbon and oxygen during purification of MWCNT by microwave treatment and water from the atmosphere in conjunction with the high adsorption properties of MWCNT [31][32][33].…”

“…Various methods were developed for raising the wettability of and functional group number on fiber surface [8][9][10][11]. Methods such as the electrochemical oxidizing [12][13][14], the oxidizing in acidic medium using nitric or phosphoric acid [15][16][17][18][19], plasma [20][21][22], and radiation [23,24] were used for developing the performance of intermediate surface between fiber and matrix. Another method is coating with thin polymer film [25][26][27].…”

Carbon Fiber (CF) is used as a strengthening material in resin composites having high performance in most industrial areas due to the fact that it has mechanical properties such as low weight, high durability, and toughness. The mechanical performances of composite materials depend on the features of fiber and matrix which composed them. The one of methods which improves the features of fiber surface is the coating on fiber surface with thin film. When the fiber was coated with electropolymer, the mechanical durability of the composite was increased. In this study, carbon fibers were electrochemically coated with polypyrrole (PPy) in the presence of sizing compound (SC) based on epoxy. During the process, it was investigated that how current, obtained coating weights and impedance data, especially capacitance, changed by the amount of SC. For this reason, different amounts of SC (%0; % 0.18; %1.8 v/v) was added into the electrolyte solution (0.1 M NaClO4-ACN) including 0.1 M Pyrrole (Py). Coating process was carried out by using Constant Potential or Cyclic Voltammetry Techniques. Other techniques for investigations were gravimetrical analysis, electrochemical impedance spectroscopy, Fourier Transform Infrared Spectroscopy (FT-IR) and Light Microscopy. At the end of the coating, the weight of coating and specific capacitance (Csp) values were 0.8 mg/g and 114 µF for % 0 of SC 10 mg/g and 57 µF for %0.18 of SC and 1.73 mg/g and 166 µF for %1.8 of SC, respectively. As a result, the coating weight and capacitance data (especially, Csp,) of carbon fiber coated with PPy were inversely changed with the amount of SC added into electrolyte.
