The preparation of the poly(vinyl alcohol)/graphene nanocomposites with low percolation threshold and high electrical conductivity by using the large-area reduced graphene oxide sh...
Publicado 2013-09-01Enlace del recursoWe report a method to prepare the poly(vinyl alcohol)/reduced graphene oxide (PVA/rGO) nanocomposites with low percolation threshold and high electrical conductivity by using the large-area reduced graphene oxide (LrGO) sheets. The large-area graphene oxide (LGO) sheets are expected to overlap bette...

Rod like attapulgite/poly(ethylene terephthalate) nanocomposites with chemical bonding between the polymer chain and the filler
Publicado 2012-08-01Enlace del recursoPoly(ethylene terephthalate) (PET) nanocomposites containing rod-like silicate attapulgite (AT) were prepared via in situ polymerization. It is presented that PET chains identical to the matrix have been successfully grafted onto simple organically pre-modified AT nanorods (MAT) surface during the i...

Non-uniform dispersion of toughening agents and its influence on the mechanical properties of polypropylene
Publicado 2014-04-01Enlace del recursoTo achieve excellent properties of polymer blends and composites, good dispersion and uniform distribution of second component or filler in the matrix are often required. However, more and more evidences reveal that uniform distribution is not always the best. To further prove this idea, in this wor...

Effect of homopolymer poly(vinyl acetate) on compatibility and mechanical properties of poly(propylene carbonate)/poly(lactic acid) blends
Publicado 2012-11-01Enlace del recursoA small amount of homopolymer poly(vinyl acetate) (PVAc) is used to compatibilize the biodegradable blends of poly(propylene carbonate) (PPC) and poly(lactic acid) (PLA). Scanning electron microscopy (SEM) and differential scanning calorimetry (DSC) results show that PVAc is selectively localized in...
