Abstract
Coefficient of friction (COF) measurements and AFM of LLDPE films containing erucamide and behenamide indicated that COF reduction is not necessarily dependent on additive coverage of the film surface. A film containing 1010 ppm erucamide yielded a kinetic COF of 0.2 without complete surface coverage, whereas a 1080 ppm behenamide film exhibited a saturated surface and higher COF. AFM showed distinct differences in crystal formation between the surface-segregated additives, with erucamide exhibiting a plate-like structure.
