Flake graphite (FG) was treated by microwave radiation in hydrogen peroxide solution and used to support stearic acid (SA) to synthesize SA/FG composites for thermal energy storage. Furthermore, the mechanism of the enhanced performance of SA/FG 3 was further revealed by monitoring functional groups of the surface of FG and demonstrated on the atomic-scale. Infrared imaging showed SA/FG 3 possessed superior thermal-regulated properties. Therefore, all these thermal properties indicate SA/FG 3 has potential for application in thermal energy storage systems.

“…The carbon region is dominated by aliphatic species, with a significant high binding energy shoulder probably associated with contributions from the nitrile, and possibly carbonyl and –CF surface functionalities. Fluorination resulted in the growth of a single F 1s state at 687 eV, indicating that the fluorine is covalently bond to the carbon surface 29…”

Unidirectional, carbon fiber-reinforced polyvinylidene fluoride (PVDF) composites were manufactured using a powder impregnation process with integrated in-line continuous atmospheric plasma fluorination of carbon IMPACT OF IN-LINE APF OF CARBON FIBERS ON UNIDIRECTIONAL, CF-REINFORCED PVDFfibers to produce unidirectional carbon fiber/PVDF tapes with a fiber volume fraction of 60 ± 2%. Carbon fiber/PVDF tapes were processed into composite laminate test specimens by compression moulding and interface-dominated composite properties were studied. Short-beam shear test results showed an improvement of up to 70% for the composite laminates containing atmospheric plasma-fluorinated T700 carbon fibers with a fluorine content of 3.7 at. %, as determined by X-ray photoelectron spectroscopy. The flexural strength and modulus of the laminated carbon fiber/PVDF composites containing APF-treated T700 carbon fibers also increased by 45% and 38%, respectively. C

“…[1,[4][5][6] It has been reported that the resultant properties of carbon fiber reinforced composites are largely dependent upon the interfacial adhesion between the carbon fiber and the epoxy matrix. Thus, an effective interface is necessary in a high-performance carbon fiber reinforced composite to guarantee effective transition of stress.…”

Surface & Interface Analysis

A polyacrylonitrile-based carbon fiber was electrochemically oxidized in an aqueous ammonium bicarbonate solution with current density of up to 2.76 A/m 2 at room temperature. X-ray photoelectron spectroscopy revealed that the oxygen content increased with increasing current density before approaching saturation. The increase can be divided into two regions, the rapid increase region (0-1.78 A/m 2 ) and a plateau region (1.78-2.76 A/m 2 ). The surface chemistry analysis showed that the interlaminar shear strength (ILSS) value of the carbon fiber/epoxy composite could be improved by 24.7%. The carbon structure was examined using Raman spectroscopy in terms of order/disorder in the graphite structure and the results indicated that the relative percentage of graphite carbon in the form of sp 2 hybridization increased above a current density of 1.39 A/m 2 . The increasing non-polar graphite carbon on the carbon fiber surface decreased the surface energy. As a result, both the surface free energy (γ T s ) and its polar component (γ p s ) decreased when current density increased above 1.78 A/m 2 . The ILSS value had no direct relationship with the nature and surface density of the oxygen-containing functional groups nor with the carbon structure. It is the surface free energy (γ T s ), especially the polar component (γ p s ), which played a critical role in affecting the interfacial adhesion of carbon fiber/epoxy composites. The ILSS value changed with increasing current density and could be divided into three distinct regions, as chemical interaction region (I), anchor force region (II) and matrix damage region (III).
