摘要： A method for transferring a carbon nanotubes aqueous phase dispersion into an organic phase dispersion includes: providing the carbon nanotubes aqueous dispersion; mixing the carbon nanotubes aqueous dispersion with a first solvent to obtain a first suspension, where the first solvent includes a hydrophilic organic solvent; mixing the first suspension with a second solvent to form two stratified phases, allow to obtain a second suspension, where the second solvent includes a hydrophobic organic solvent; mixing the second suspension with a third solvent to obtain a third suspension; and subjecting the second suspension or the third suspension to dispersion treatment to obtain a carbon nanotubes organic dispersion, thereby realizing solvent transfer of the carbon nanotubes dispersion from aqueous to organic phase. The method can transfer the carbon nanotubes aqueous dispersion into the organic dispersion, and the transfer efficiency is 70%-95%.

摘要： The present disclosure relates to a polymeric blend composite comprising Poly Ether Ketone/Poly-(2,5-Benzimidazole) containing pre-treated multi walled carbon nanotubes (MWCNTs) between 0.5 to 5 wt % were melt processed on a twin-screw extruder and granules so obtained were injection molded to determine heat deflection temperature (HDT) of these composites and storage modulus using DMA. It was found that HDT and storage Modulus for so produced reinforced blends were unexpectedly extremely high as compared to PEK/ABPBI blends without MWCNTs.

摘要： The present disclosure relates to sustainable and green polylactic acid-based membranes embedded with self-assembled positively and negatively charged multiwalled carbon nanotube/graphene oxide nanohybrids for the removal of organic and inorganic nutrients from wastewater, and methods of synthesis of the same. A positively charged multi-walled carbon nanotube/graphene oxide (f-MWCNT/GO) nanohybrid-based mixed matrix membrane can comprise a self-assembled multi-walled carbon nanotube and graphene oxide (f-MWCNT/GO) nanohybrid, and a polylactic acid (PLA) membrane matrix. The f-MWCNT/GO nanohybrid is integrated into the PLA membrane matrix to form the positively charged mixed matrix membrane. A negatively charged multi-walled carbon nanotubes (f-GO/MWCNTs-COOH) nanohybrid-based mixed matrix membrane can comprise a positively charged Graphene Oxide and negatively charged multi-walled carbon nanotube-COOH (f-GO/MWCNTs-COOH) nanohybrid, and a polylactic acid (PLA) membrane matrix. The f-GO/MWCNTs-COOH nanohybrid is integrated into the PLA membrane matrix to form the negatively charged mixed matrix membrane.
