A Haake Rheomix® 600 internal mixer with two roller rotors was used for the preparation of the PLA/organoclay hybrids with different compositions. This mixer is attached to a measuring drive unit Haake Rheocord® 9000. The processing temperature was set at 170 °C. The rotor rotating speed and mixing time were fixed at 100 rpm and 10 min. The components were first dried in vacuum and then dry blended at predetermined compositions and subsequently melt mixed in the mixer under the protection of nitrogen atmosphere. After mixing, the samples were dumped out and compressed into about 2-mm-thick plates by a calender for further characterization.
