“…This technique has become rather popular for the characterization of the surface oxygen functionalities of activated carbon [45,49,79,84,94,[124][125][126][127][128][129][130][131][132]. During a TPD experiment, surface oxygen groups on carbon materials are decomposed upon heating by releasing CO 2 at lower temperatures and predominantly CO at higher temperatures and in some cases H 2 O and H 2 , at different temperatures [45,49,52,61,67,84,93,[132][133][134][135].…”

“…However, it is not easy to interpret the IR spectra because the peaks obtained are usually a sum of the interactions of different types of groups [67,130,173]. Furthermore, IR does not provide quantitative information about the presence of individual functionalities on the carbon surface [59].…”

“…It is expected that the recycled carbon fibres has a lower surface energy since their surface oxygen concentrations are lower from the XPS measurement [25,26]. The similar surface energies are most likely caused by a higher surface area of the recycled carbon fibres according to Wenzel's theory [27,28], which relates surface area to contact angle (Eq.8).…”

The structure-property relationship for recycled carbon fibres is investigated by characterisation of the structure changes induced by the pyrolysis recycling process. Two important factors influencing the properties of recycled carbon fibres are identified for various recycling processes: oxidative effect and thermal effect. The oxidative effect results in surface defects, and the surface defects causes a reduction in tensile strength and lateral crystallite size. The thermal effect of the recycling process results in an expansion in the distance between graphite layers and a decrease in surface oxygen concentration, which would lead to a drop in interfacial shear strength with epoxy resins. The tensile strength of recycled carbon fibres has a strong correlation with the intensity ratio of the D and G bands of the Raman spectra (ID/IG). With an increase in ID/IG, the tensile strength of recycled carbon fibre decreases linearly.

“…The water contact angle hysteresis Dh (Fig. 2), which is the difference between h a and h r , decreases with increasing APO exposure time suggesting an increase in surface homogeneity, [52,53] most likely due to a more homogeneous distribution of the surface oxides on the fibre surface as a result of APO.…”

Continuous atmospheric plasma oxidation (APO) was used to introduce oxygen functionalities to the surface of carbon fibres in an attempt to enhance interfacial adhesion between carbon fibres and polyamide-12 (PA-12). APO only affects the surface properties of the fibres while their bulk properties remained unchanged. Contact angle and f-potential measurements demonstrated that APO-treated fibres became significantly more hydrophilic due to the introduction of polar oxygen-containing groups on the fibre surface, which also resulted in an increase of surface energy on the carbon fibres. The interfacial shear strength of single carbon fibre/PA-12 model composites, determined by single fibre fragmentation tests, showed an increase from 40 to 83 MPa with up to 4 min of APO treatment time which confirms that the fibre/matrix interfacial adhesion was enhanced. This highlights that the incorporation of APO into composite manufacturing will allow tailoring of the fibre/ matrix interface.
