摘要: Abstract This work examines the effects of kinetic parameters on assembly copper nanowires (CuNWs) in discrete phases and at interface two distinct blend systems: a high interfacial tension poly(lactic acid), PLA, /low density polyethylene (LDPE) low PLA/poly(butylene adipate-co-terephthalate), PBAT. CuNWs were synthesized through electrodeposition porous alumina oxide template. Considering surface polarity polymer melts hydrophilicity CuNWs, particles should be located more polar phase (PLA PLA/LDPE or PBAT PLA/PBAT). TEM images confirm that when are initially premixed with phase, they remain stable fashion irrespective system. However, less to investigate effects, different behaviors observed; blends, partition between both phases, while PLA/PBAT assemble PLA phase. The mixing time shear rate these phenomena examined, importantly, for blend, it is shown can assembled interface. mechanism cylindrically shaped result enhanced bulk migration slow across
