(Elsevier, 2016)In the present work, a new method is developed for the preparation of polyethylene magnetic nanocomposites by in situ polymerization. Carbon nanotubes (CNTs), synthesized by the chemical vapor deposition method using ...
-
(Elsevier, 2017)In this study, polycaprolactam (PA6) nanocomposites with thermally reduced graphene oxide (TrGO) and carbon nanotubes (CNTs) were prepared by melt blending with the aim of obtaining films with improvements in permeability ...
-
(Universidad de Chile, 2012)En los últimos años, los materiales con propiedades antimicrobianas han generado gran interés, ya sea para su uso en envasado de alimentos o insumos médicos. Mediante nanocompuestos que incorporen la fase anatasa del dióxido ...
-
(Universidad de Chile, 2008)La necesidad por encontrar protección ante la corrosión ha sido un gran desafío para la industria de revestimientos en estos días, por esto se han buscado soluciones que sean ambientalmente amigables, eficientes, de bajo ...
-
(SOC PLASTICS ENG INC, 2003-04)New types of compatibilizers based on functionalized polypropylene (PP) were synthesized by radical melt grafting either with monomethyl itaconate or dimethyl itaconate. The effect of these new modified PP compounds were ...
-
(ELSEVIER SCIENCE BV, 2005-02-15)New cyclopalladated complexes (Pd-A, Pd-B, Pd-C) were used as catalysts in ethylene polymerization. All of them show good activity, especially at a temperature of 80 degreesC. The molecular weight and molecular weight ...
-
(Elsevier, 2016)This paper proposes the development of isotactic polypropylene (iPP) nanocomposites with magnetic carbon-based hybrid fillers, which contain magnetite, by melt mixing at 190 degrees C. The carbon-based fillers such as ...
