Linear low-density polyethylene (LLDPE) films containing boron nitride nanoplatelets (BNN) and were fabricated by continuous melt extrusion. The inclusion of BNN led to 10-fold increase of the in-plane thermal conductivity of the nanocomposite (7.7 W/m.K vs. 0.3 W/m.K for pure LLDPE). To increase the surface area available for convective heat transfer, micro-textured films (T-BNN) were produced from a micro-patterned die. Nanoplatelets oriented parallel to the film machine direction. Nanocomposite films lose ductility for a very high BNN content, but retain their stiffness and tensile strength as compared to the base LLDPE. BNN addition to the LLDPE decreased coeffiecent of friction by 50%, and mixrotextures raised this decrease by 7% more.
