Porous biomaterials by using supercritical fluids emulsions [PDF]

, 2006
Different authors have investigated the production of porous polymeric materials using supercritical CO2 as a solvent and/or foaming agent. The removal of the template phase is simple since CO2 reverts to gas phase upon depressurization.

Continuous supercritical hydrothermal synthesis of nanomaterials

, 2019
The synthesis of minerals has been pushed in the last decade by their insertion into new and advanced materials as mineral fillers in ceramic, polymer, paper, cosmetic, pharmaceutical, cements … [1]. Up to now, the main synthesis method was the conventional batch synthesis characterized by long reaction times (few hours).

Mechanically robust biochar‐modified polystyrene foam with enhanced flame retardancy using halogen‐free additives

Polymer International, EarlyView.
Halogen‐free biocomposite polystyrene foams were fabricated via pilot‐scale supercritical CO2 extrusion using expandable graphite, melamine polyphosphate, biochar, and recycled polymer. The optimized formulation exhibited refined cellular morphology, enhanced flame retardancy (limiting oxygen index of 25%, rapid self‐extinguishing), and improved ...
