“…Pairing CNTs with such systems having photoactive properties can lead to the development of devices for energy conversion, analyte sensing or catalytic systems. Several studies have thus been conducted in which CNTs are non-covalently functionalized by metalloporphyrins [213][214][215][216][217][218][219][220][221][222][223][224][225][226][227][228] or phthalocyanines [220,[229][230][231][232].…”

“…5b further support the formation of the CNTs/PLA nanocomposites. The fluorescence quenching obtained for composites in THF solution can also be compared with the reported values in the literature for the corresponding materials obtained through non-covalent method [15]. The CNTs quench the emission of ZnP unit of the composite in solution.…”

“…As is well known, porphyrin derivatives are widely used in preparation nanocomposites by non-covalent functionalization method for their p-p interactions with CNTs [14,15]. Here we report the preparation of CNTs/PLA nanocomposites with non-covalent method.…”

“…To establish an efficient approach to disperse CNTs without destruction of the CNTs structure, non-covalent functionalization based on the p-p stacking interactions has been exploited [13]. The polymers used in this strategy usually contain conjugated moieties such as pyrene, porphyrin, etc., [14,15]. Pan prepared polymeric composite using pristine multi-walled carbon nanotubes and triphenylene core PLA with a non-covalent functionalization method [16].…”

The polymeric composites with four-armed star polylactic acid (PLA) immobilized on the surface of carbon nanotubes (CNTs) were constructed by a simple ultrasonic process using non-covalent method. The four-armed star polylactic acid was prepared by ring-opening polymerization of lactide using zinc ptetraaminophenylporphyrin (ZnP) as initiator and stannous octoate as catalyst. Due to the strong p-p interactions between CNTs and zinc porphyrin of star PLA, the CNTs/PLA composites can be easily obtained while the intrinsic graphitic structure of CNTs is retained. The CNTs/PLA nanocomposite was studied via infrared spectrum (IR) and thermogravimetric (TG) analysis. UV-Vis and fluorescence demonstrate that the porphyrin probably strongly anchored on the side walls of the nanotubes. Optical studies further promise the non-covalent interactions. Meanwhile, morphology studies with and scanning electron microscope (SEM) show that CNTs are dispersed well in the polymer. This convenient non-covalent method may be useful for the preparation of CNTs-polymer hybrid without the destruction of the intrinsic graphitic structure of the pristine CNTs.

“…Covalent functionalization using oxidizing acids at high temperature causes defects on the walls of the carbon nanotubes and their length decreases, therefore their electrical and mechanical properties are degraded [13,14]. Non-covalent functionalization by adsorption of surfactant or polymers and use of mild ultrasonic treatments, centrifugation and filtration does not disturb the -stacking or the lengths of CNTs, thus, maintaining intrinsic properties of the CNTs [15][16][17].…”
