Article Synopsis
  • - Polyimides are promising materials for gas separation membranes due to their selective permeability and ability to operate under various temperatures and pressures, and current research is focusing on enhancing their performance through various fillers.
  • - Researchers tested butylcalix[n]arene macrocycles (PTBCs) with different sizes as fillers in a thermoplastic polyimide to create nanocomposite membranes, using concentrations from 1-9 wt%.
  • - The study involved preparation of films through a pre-mixing and solvent casting process, followed by characterization of their properties and gas transport, showing that the addition of these nanoporous fillers improved molecular transport efficiency.

Thermal degradation processes of poly(ether sulfone) random copolymers having different molar amount of diphenolic acid (DPA) units were studied by direct-pyrolysis/mass spectrometry, stepwise pyrolysis-gas chromatography/mass spectrometry and thermogravimetric techniques. Results highlighted that thermal degradation processes occur in the temperature range from 370 to 650 °C, yielding a char residue of 32-35 wt%, which decreases as the mol% of DPA units rises. The pyrolysis/mass spectra data allowed us to identify the thermal decomposition products and to deduce the possible thermal degradation mechanisms.
