“…Although POK is chemically and physically stable under inert conditions at room temperature, it shows poor thermal stability when exposed to heat and air, which limits its applications in some cases. Lim et al fabricated antioxidant‐grafted GOs by grafting hindered phenol and hindered amine onto the surface of GOs and found that the antioxidant‐grafted GOs were effective in improving the thermal properties of POK (Figs (b) and (c)). The reason could be ascribed to the antioxidant functional groups which can react with various kinds of free radicals and the heat and mass barrier effect of GOs having ultrathin sheet shapes.…”

Polyketone (POK), a new environment‐friendly engineering plastic produced from carbon monoxide (CO), can be used for various applications including packaging, fibers and technical items. Due to its exceptional balance of mechanical properties and high chemical resistance, POK holds great potential to be one of the most promising candidates for high‐performance and multifunctional polymer materials. The introduction of other polymer materials, reinforcing fibers or micro‐ and/or nanofillers into the POK matrix is a powerful method for obtaining new POK‐based materials with specific characteristics and satisfactory improvements in properties. This article summarizes and highlights the recent advances and efforts in research and development in the field of POK blends, POK composites and POK blend‐based composites. The applications of POK materials and outlook are also summarized and discussed. © 2018 Society of Chemical Industry

“…Given the extraordinary 2D nanoplate structure, excellent mechanical properties and strong hydrophilicity, GO has been regarded as a desired candidate to design the advanced membranes [28][29][30]. As reported, several novel methods have been developed to prepare GO with low cost, making it more competitive and accessible than CNT [31,32]. Preferentially, a small dosage of GO is strongly recommended to reduce the cost for the fabrication of GO-modified hybrid membranes with improved performance.…”

“…Estimations of mechanics, chemical resistance, heat distoration stability, tribological property, and gas/liquid barrier property indicate that POK is a suitable candidate for new generation of engineering plastics applied in automotive, fibers, packaging areas, and blend applications . Modifications of POK engineering plastics have been tackled properly via, in particular, the pathways of elastomer toughening and nanoparticles reinforcement . Undoubtedly, the flame retardancy is of significant for the practical application of POK materials.…”

Aliphatic polyketone (POK) is a new engineering plastic owning outstanding mechanics, chemical resistance, and gas/liquid barrier properties. However, analogous to other polymers, the nature of combustion severely restricts the widespread application of POK. Herein, the diethyl zinc phosphinate (ZnPi) was compounded with three grades of POKs, which were different among each other in viscosity as low (L), medium (M), and high (H) levels, by melt mixing. It is intriguing to suggest that increasing the viscosity of POK could remarkably improve the dispersion homogeneity of ZnPi, which was beneficial to superior flame retardancy, simultaneously with comprehensive mechanical properties. For the H-POK matrix, only 10% well-dispersed ZnPi resulted in a V0 ranking with a good maintenance of its notched impact strength, whereas the load of ZnPi for reaching V0 rank increased to 14% in L-POKs and M-POKs and the mechanical performances decreased mildly. By a combination of scanning electron microscopy (SEM), Fourier-transform infrared (FTIR), thermogravimetric analysis (TGA), and cone calorimetry, it is well revealed that the flame retardancy induced by adding ZnPi could mainly ascribe to the formation of various zinc phosphate species. This work exploits a facile and feasible method for fabrication of antiflame engineering plastics, which will be promising for large-scale applicability of high-performance POK materials.
