Up‐Scaling of Melt‐Spun LDH/HDPE Nanocomposites

Layered double hydroxide (LDH) was melt‐mixed with high‐density polyethylene (HDPE) using a co‐rotating twin screw microcompounder with a volume of 15 ml (small‐scale) and using a co‐rotating twin screw extruder with a production rate of 10 kg h −1 (large‐scale). The nanocomposites were further melt‐spun with a piston‐type spinning device and a universal laboratory high‐speed spinning device with respect to the scale of the nanocomposite preparation. The spinnability and mechanical properties of the nanocomposites were found to be comparable with the neat polyethylene. Bicomponent fiber preparation was also carried out, in which neat polyethylene was set as core and the nanocomposite as sheath.
