“…Hindered Amine Light Stabilizer (HAS) molecules were covalently linked on the outer surface of multi-walled carbon nanotubes (CNTs), and thus obtained multi-functional fillers (HAS-f-CNTs) were compounded with Ultra High Molecular Weight Polyethylene (UHMWPE) to get composite films [20]. The success of the grafting reaction of the HAS molecules was scored through spectroscopic and thermo-gravimetric analyses.…”

The review briefs about the status of worldwide studies into impact of carbon nanotubes (CNTs) on the oxidation environments of polymeric composites and biological objects. CNTs reveal the higher antioxidant capacity preferably operating as a thermo-stabilizer in polymers and radical scavengers in vivo. In this respect, CNTs may be compared with strong commercial and natural well-known antioxidant moieties.

“…The relative degree of functionalization or defects in the nanotubes can be characterized by the intensity ratio of the D‐band and G‐band ( I D /I G ). I D / I G increased from 1.204 (pristine MWNTs) to 1.254 (F‐MWNTs), which reveals the formation of more defects or functional groups on the MWNTs surface after the oxidation treatment .…”

The Nylon 6 (PA6)/the functionalized multiwalled carbon nanotubes (F‐MWNTs) fibrous membranes were fabricated by electrospinning, and then incorporated into an epoxy matrix. Their morphology, thermal stability, mechanical properties, thermal conductivities, and electrical resistivity were investigated. The electrospun PA6/F‐MWNTs fibers performed as a skeleton in the epoxy matrix, and the well interfacial adhesion between the epoxy matrix and the PA6/F‐MWNTs fibers leads to high mechanical properties of composites. The PA6 serves as an intermediate layer and alleviates the modulus mismatch between the stiff MWNTs and the soft epoxy matrix. The thermal conductivities of the epoxy composites increase by 27.3, 35.0, and 36.1%, respectively, with 0.5, 1 and 1.5 wt% F‐MWNTs loading in the PA6/F‐MWNTs fibers. At the same time, the PA6 simultaneously retains the high electrical resistivity of these epoxy composites. POLYM. ENG. SCI., 56:1259–1266, 2016. © 2016 Society of Plastics Engineers

“…Particularly, the modification of CNTs surface can be obtained through different methods, such as defect , covalent , and non‐covalent functionalization. This strategy, besides facilitation of the obtainment of an uniform dispersion of CNTs, allows to produce CNT‐based nano‐hybrids that combine the characteristics of CNTs with those of grafted functional groups .…”

Silanol polyhedrad oligomeric silsesquiosane terminated with phenyl rings (phPOSS) has been considered as dispersing agent for carbon nanotubes (CNTs) in polyamide (PA) matrix. Two different approaches have been followed for the introduction of the phPOSS molecules: a “classical” approach which involves the introduction of the dispersing agent during the melt mixing, and an “innovative” approach, consisting in the immobilization, either covalent and non‐covalent, of phPOSS molecules onto CNTs surface. The properties of PA‐based nanocomposites, containing free phPOSS molecules and phPOSS molecules immobilized onto the CNTs outer surface, have been evaluated through rheological, mechanical, thermo‐mechanical, and morphological analyses. Obtained results highlight the effectiveness of the immobilization of the dispersing molecules onto the surface of the CNTs because of the enhancement of the interfacial interaction between the nanofillers and matrix. The preferential localization of the phPOSS molecules at the interface between the nanofillers and polymer chains helps the CNTs dispersion during melt processing and promote the stress transfer across the interface, leading to the obtainment of nanocomposites with enhanced mechanical performance.
