In contemporary research, there has been a surge in the efforts to design novel porous materials as adsorbents for CO2 capture. Polyamides are a class of robust polymers that are easy to synthesize from readily available starting materials. These have CO2-philic amide functional groups and hence are being considered as materials for CO2 adsorption and storage. Herein, we report facile and efficient...
Polyamide 11 (PA11) nanocomposites reinforced with Cellulose Nanocrystals (CNC), dodecanoic acid surface modified CNC (CNC_d), and CNC with methyl laurate (CNC + ML) as plasticizer were fabricated. With the addition of CNC alone, tensile modulus and strength of the PA11 were improved, but the toughness decreased at high CNC concentration. Using CNCs that were surface modified, the tensile modulus...
Two kinds of new electroactive polyamides were synthesized from a novel diphenylamine-fluorene skeleton bis(ether amine) monomer “N,N-bis((4-aminophenoxy)phenyl)-2-amino-9,9-dimethylfluorene” with cycloaliphatic and aromatic dicarboxylic acids, respectively. These polyamides were highly soluble in many organic solvents and could be solution-cast into transparent and flexible films. These films were...
The structure and function of the thin polymeric functional layer in reverse osmosis membranes depend on the kinetics of the interfacial polycondensation (IP) reaction by which the film is formed. It has been a challenge to achieve a quantitative understanding of these kinetics because of the high velocity of the reactions and the complex geometry of the support membrane in which the reaction takes...
The prevalent way to enhance interface interaction of immiscible polymer blend is adding some low molecular weight compatibilizers with “soft” nature, unfortunately throwing negative effects on the final mechanical strength. Here, an interfacial interlocking design strategy for immiscible polypropylene (PP)/polyamide (PA) blend is proposed. The formation process involves aryl amide-based compounds...
