2.3 Preparation of the composite specimens
The 25 wt.% SCG, NSCG, and ASCG were mechanically mixed with PP,
respectively. Then they were processed at 190 ℃ 60 rpm for 15 minutes in
a torque rheometer with a reverse rotating head. Finally, the obtained
samples were pressed into thin sheets at 190 °C for 5 minutes with a
pressure of 10 MPa, and then taken out for use after cooling.
