“…The peak at 1,630 cm -1 is ascribed to stretching vibrations of C=C bond, which form the framework of carbon nanotubes sidewalls. The peak at 1,400 cm -1 corresponds to deformation vibrations of C-H [13]. Compared with the spectrum of pristine MWCNTs, new peaks at 1,740 and 3,440 cm -1 are attributed to stretching vibrations of C-O bond and stretching vibrations of O-H bond in carboxylic acid groups of MWCNTs-COOH, respectively [14].…”

The polyimide (PI)/carboxyl-functionalized multi-walled carbon nanotube (MWCNTs-COOH) nanocomposite films were synthesized by situ polymerization method. The results showed that the incorporation of MWCNTs-COOH greatly enhanced thermal stability and mechanical property of PI. PI/MWCNTs-COOH nanocomposites exhibited better tribological properties under seawater lubrication than other conditions because of excellent lubricating effect of seawater. Besides, the wear resistance of PI under seawater lubrication had been greatly improved by filling MWCNTs-COOH, because strong interfacial adhesion between PI matrix and MWCNTs-COOH nanofillers could transfer load effectively between contact surfaces. In particular, when the content of MWCNTs-COOH was 0.7 wt%, the corresponding PI/ MWCNTs-COOH nanocomposites had the best tribological properties under seawater lubrication. Graphical Abstract The polyimide (PI)/carboxyl-functionalized multi-walled carbon nanotube (MWCNTs-COOH) nanocomposite films were synthesized by in situ polymerization using 4,4 0 -oxydianiline (ODA), carboxyl-functionalized multi-walled carbon nanotube (MWCNTs-COOH) and pyromellitic dianhydride (PMDA). The tribological properties of PI/MWCNTs-COOH nanocomposite films were measured under dry sliding condition, pure water condition and seawater lubrication condition. This study can provide some guidance to develop polymer materials with excellent wear resistance suitable for ocean environment.

“…However, strength and toughness in most materials are mutually exclusive, which is not desirable for high‐performance applications. For example, polymers reinforced by inorganic fillers, such as clay, graphene oxide, and carbon nanotubes, have improved modulus and tensile strength, but at the same time the ductility of the polymers may be inevitably sacrificed, leading to impaired toughness. On the other hand, brittle polymers can be effectively toughened by the addition of rubber phases, which however tend to plastically deform more easily .…”

Strength and toughness are the two most important prerequisites for structural applications. Unfortunately, these two properties are often in conflict in materials. Here, an effective and yet practical strategy is proposed to simultaneously strengthen and toughen poly(l-lactide) (PLLA) using a simple rigid-rubber "reinforcing element." This element consists of a rigid graphene oxide (GO) sheet covalently coupled with poly(caprolactone-co-lactide) (PCLLA) rubbery layers, which can be easily synthesized and incorporated into PLLA matrix to develop composites with well-tailored GO/PLLA interfaces. It is demonstrated that by adding the "reinforcing element," i.e., GO-graft-rubber-graft-polyd-lactide), PLLA exhibits higher strength and higher toughness, which could be attributed to the synergy of rigid GO and rubbery PCLLA working in tandem during deformation. It is further demonstrated that this strategy can also be applied to other filler systems, such as clay and particulate polyhedral oligomeric silsesquioxane, and other polymer systems, such as poly(methyl methacrylate). The strategy could be considered as a general design principle for reinforcing materials where both strength and toughness are the key concerns.

“…These absorbers possess favorable absorption performance and are widely used in the applications aforementioned, but they can be used only at room temperature. Another kind of microwave absorption coatings, which is composed of matrix and dielectric absorbers, such as short carbon fibers, carbon black, and carbon nanotube, could be used at high temperatures. However, the application of this kind of coatings in the high temperature environment is still challenged taking account of the weak adhesion between the coating and the metal substrate caused by the thermal expansion coefficient mismatch and the unsatisfactory absorption performance as compared to the coatings containing magnetic lossy absorbers.…”

Heat resistant microwave absorbing coatings were prepared by brushing and thereafter heat treatment, using epoxy modified organic silicone resin as binding material, short carbon fibers (C sf ) as absorbers, talcum powder and glass powder as filling materials. The mechanical and dielectric properties of the coatings before and after heat treatment at 600 C for 10 mins were studied. The results showed that the adhesive power after heat treatment enhances remarkably, both the real (e 0 ) and imaginary (e 00 ) parts of the permittivity of the coatings increase with increasing C sf content in the frequency range of 8.2-12.4 GHz. The calculation value of the reflection loss as single layer absorber indicates that epoxy modified organic silicone resin coatings containing short carbon fibers could be a promising radar absorbing material applied at high temperature.
