“…Analogous behaviour of mechanical enhancement has been reported in the literature for different polymer/SWCNT composites [33,43]. Our experimental data reveal a non-linear growth of E 0 with SWCNT content, the increase being more pronounced at low concentrations.…”

“…This observation reveals that a more uniform and fine dispersion of the SWCNTs improves the interfacial adhesion between the CNTs and the matrix and restricts the thermal motion of the PEEK chains, thereby leading to composites thermally more stable. Similar enhancements in the thermal stability attributed to a more homogeneous distribution of the CNTs have been reported for Nylon 6/MWCNT [32] and PU/MWCNT [33] composites. Apart from the preparation procedure, other factors seem to affect the decomposition process.…”

New poly(ether ether ketone) (PEEK) based composites have been fabricated by the incorporation of single-walled carbon nanotubes (SWCNTs) using melt processing. Their structure, morphology, thermal and mechanical properties have been investigated. Scanning electron microscopy observations demonstrated a more uniform distribution of the CNTs for samples prepared following a processing route based on polymer ball milling and CNT dispersion in ethanol media. Thermogravimetric analysis indicated a remarkable improvement in the thermal stability of the matrix by the incorporation of SWCNTs. Differential scanning calorimetry showed a decrease in the crystallization temperature with increasing SWCNT content, whilst no significant changes were observed in the melting of the composites.

“…[13,14] Today, the PU paint is probably the most popular choice for a topcoat and it is of interest to modify its properties. Addition of CNTs can not only improve its mechanical properties but also modify its electrical properties and help with a problem of electromagnetic interference shielding.…”

The functionalization of multi‐walled CNTs in O2/Ar and H2O/Ar low pressure capacitive discharges was studied by XPS and FT‐IR. The pristine and functionalized CNTs were used as fillers in polyurethane paints. Successful plasma functionalization was confirmed by changes in atomic composition and chemical shift of the XPS atomic signals. The functionalization was indicated also by the shift of IR absorption peaks corresponding to the motion of carbon skeleton, especially the peak at about 1 560 cm−1. The presence of carbonyl was confirmed by IR absorption peak at 1 723 cm−1 only for O2/Ar plasma. The plasma functionalized CNTs increased significantly the universal and plastic hardness of the CNTs reinforced polyurethane as compared to the composites with pristine CNTs.

Recently, the use of thermal conductive polymeric composites is growing up, where the polymers filled with the thermally conductive fillers effectively dissipate heat generated from electronic components. Therefore, the management of heat is directly related to the lifetime of electronic devices. For the purpose of the improvement of thermal conductivity of composites, fillers with excellent thermally conductive behavior are commonly used. Thermally conductive particles filled polymer composites have advantages due to their easy processibility, low cost, and durability to the corrosion. Especially, carbon-based 1-dimensional nanomaterials such as carbon nanotube (CNT) and carbon nanofiber (CNF) have gained much attention for their excellent thermal conductivity, corrosion resistance and low thermal expansion coefficient than the metals. This paper aims to review the research trends in the improvement of thermal conductivity of the carbon-based materials filled polymer composites.
