Supercritical CO 2 foaming of metallocene cyclic olefin copolymer: Processing window, cellular morphology, and functional properties
Metallocene Cyclic Olefin Copolymer foams (mCOC) were produced using supercritical CO 2 (scCO 2 ), and the effects of temperature, pressure, and impregnation time on morphology and properties were systematically investigated. The minimum relative density was achieved at 130°C, 13.8 MPa, and 300 min, producing a d...
