Hybrids of Mg–Al-layered double hydroxide and multiwalled carbon nanotube as a reinforcing filler in the l-phenylalanine-based polymer nanocomposites

The influence of multiwalled carbon nanotubes‐NiCoAl layered double hydroxide hybrids on fire safety performance of poly(ethylene‐co‐vinyl acetate) composites

“…The TG profile of NiCoAl LDH can be divided into two stages. The weight loss in the first stage from 50°C to 200°C is attributed to the loss of physisorbed and interlayer water and the dehydration of the brucite‐like layers . The main weight loss from 200°C to 400°C accompanied with the maximum peak at 272°C can be ascribed to the decarbonation and dehydroxylation of NiCoAl LDH to produce metal oxides.…”

“…Except for the simple combinations of CNT and LDH systems, the development of CNTs‐LDH hybrids that combine CNTs with LDHs, by means of co‐precipitation method, urea precipitation method and drying grinding method, has shown lots of advantages and drawn much attention for their promising applications as pseudocapacitor, catalysis and new additives of polymeric matrix . For example, CNTs‐LDH hybrids have exhibited efficiency in reinforcing the mechanical properties, thermal stability and flame retardancy of polymeric matrices.…”

Synthesis of a carbon nanotubes/ZnAl-layered double hydroxide composite as a novel flame retardant for flexible polyurethane foams

“…For the CNT/ZnAl‐LDH composite, it undergoes a dehydration process and thermal decomposition of low‐molecular weight compounds mainly from the PSS below 300°C. With increasing temperature, the de‐hydroxylation process and the removal of interlayer carbonate anion occur with the maximum weight loss temperature at 425 and 528°C, respectively …”

“…[22][23][24][25] In addition, the CNT/LDH hybrid composites have also exhibited efficiency in enhancing the thermal stability of poly(amide-imide) and the flame retardancy of polypropylene. [26,27] Although previous work provides important insights into the improvement of flame retardancy of polymer nanocomposites with LDHs and CNTs, the effect of CNT/LDH composites on the thermal properties and flammability performance of polymeric materials are not well known. In the present study, a novel strategy was proposed to prepare a stable suspension of carbon nanotubes/zinc-aluminum LDH (CNT/ZnAl-LDH) composite in liquid media by embedding CNTs into ZnAl-LDH nanosheets, just through a simple co-precipitation method of Zn 2+ and Al…”

“…A strong electrostatic force between the two components and the interfacial bridging effect of the surfactants are account for the formation of hybrid composites . In addition, the CNT/LDH hybrid composites have also exhibited efficiency in enhancing the thermal stability of poly(amide‐imide) and the flame retardancy of polypropylene …”
