“…This change may tune the phase interaction between CNT and other polymer matrices, and thus may make CNT@ALG a novel filler to reinforce polymers and improve their mechanical properties. Generally, it has been a common method to graft hydrophilic polymers, such as PEG-based polymers [ 37 ] and gelatin [ 26 ], on the surface of CNT to improve its dispersion state. Thus, we are sure that the prepared CNT@ALG has great potential in polymer composites and realizes the improvement of mechanical properties, which may broaden the application of CNT in reinforced nanocomposites.…”

“…Furthermore, the PDA film contains abundant functional groups and can react with many other molecules or particles, and thus this method has been widely called the “mussel inspired” method and has been used to realize the surface functionalization of various materials [ 24 , 25 ]. For example, gelatin molecules were grafted on the surface of PDA-modified carbon nanotube via Michael addition reaction between the amino groups of gelatin and the quinone units of PDA [ 26 ]. More interestingly, the “thiol-Michael” click reaction is also a widely used mild method to prepare various functional materials [ 27 , 28 , 29 ].…”

Carbon nanotubes (CNTs) have attracted great interest in biomedical fields. However, the potential toxicity and poor dispersion of CNTs have greatly limited its application. In this work, a mussel-inspired method combined with the “thiol-Michael” click reaction was used to modify the surface of CNT and improve its properties. Firstly, a CNT was treated with dopamine, and then alginate grafted with L-cysteine was anchored onto the surface of CNT via click reaction, which realized the long-time dispersion of CNT in water. Furthermore, the in vitro test also demonstrated that the alginate may improve the biocompatibility of CNT, and thus may broaden the application of CNT in the biomedical field.

This work reports our recent efforts on the preparation of functionalized multi‐walled carbon nanotubes (f‐CNTs) and its application in improving the fire, conductive, and mechanical performance of epoxy resin (EP) composites in combination with graphite sheets (GSs). The addition of hybrid carbon nanomaterials can effectively improve the mechanical properties of epoxy. Consequently, when the mass fraction of f‐CNTs/GSs is 3.9 wt%, the limiting oxygen index (LOI) value is increased to 27.4%, and the tensile strength and notched impact strength of epoxy are increased by 33.5% and 44.8%, respectively. Increasing the content of carbon nanomaterials can further improve the flame retardancy and electrical conductivity of EP composites. For the sample containing 11.0 wt% f‐CNTs/GSs, the electrical conductivity is further increased to 1.7 × 10−3 S/cm, which can be regarded as conductive materials. The LOI value is reached to 28.6%, with peak heat release and total heat release reduced by 26.4% and 16.4%, respectively.
