Summary
A novel method for preparing all-polymer nanocomposites was described. The technique is based on enhanced susceptibility to deformation of a polymer having a lowered number of entanglements in the amorphous phase. Polymer powder remaining in the solid state was blended with a second molten polymer, and the shearing forces during compounding deformed the powder grains into nanofibers. After solidification of the matrix all-polymer nanocomposite was obtained. The effectiveness of the method was demonstrated on the example of ultra-high molecular weight polyethylene (PE-UHMW) composite containing PP nanofibers, produced in situ during compounding.
