Compatibilization and ultraviolet blocking of PLA/PCL blends via interfacial localization of titanium dioxide nanoparticles

In this work, the effect of TiO 2 addition over morphological and ultraviolet (UV) blocking properties of poly(lactic acid) (PLA) and poly(ɛ‐caprolactone) (PCL) blends was investigated. The micrographs showed a partially co‐continuous structure in the PLA/PCL blend with 42/58 (wt %/wt %) and the TiO 2 nanoparticles addition leads to a structural phase inversion, i.e., continuous PCL and partially continuous PLA with a dispersed portion. TiO 2...
