Fabrication of biodegradable poly (lactic acid)/carbon nanotube nanocomposite foams: Significant improvement on rheological property and foamability

Recently, biodegradable macromolecules have been highly desired as a promising alternative for traditional oil-based plastics to work out the eco crisis and biological health problems triggered by microplastics. Herein, we presented a simple, effective, environmentally friendly and CO2-based foaming methodology for fabricating ultra-low-density poly (lactic acid)/carbon nanotube (PLA/CNTs) nanocomposite foam. By the gradual incorporation of...
