Distribution of an antioxidant in polypropylene/ethylene-octene copolymer blends studied by atomic force microscopy-infrared.

In this work, the microscopic distribution of antioxidant 1010 (AT1010) in blends of isotactic polypropylene (iPP) with an ethylene-octene copolymer (POE) was investigated using the atomic force microscopy-infrared (AFM-IR) technique. Pellets of an iPP/POE blend containing AT1010 at a mass ratio of 79.5 : 20 : 0.

Carbon-based dots for the electrochemical production of hydrogen peroxide.

In this study, natural graphite was liquid exfoliated in the presence of single-layer carbon-based dots (CDs), which were used as intercalators. It was found that graphene of mainly single-layer has been obtained, on which lots of CDs were deposited. Combining the unique properties of these two materials, the CDs deposited on graphene (G/CDs) are proved to be outstanding catalysts for the electroreduction of oxygen to HO.

Largely improved tensile properties of chitosan film via unique synergistic reinforcing effect of carbon nanotube and clay.

In this work, a great synergistic effect of 2D clay platelets and 1D carbon nanotubes (CNTs) on reinforcing chitosan matrix has been observed for the first time. With incorporation of 3 wt % clay and 0.4 wt % CNTs, the tensile strength and Young's modulus of the nanocomposites are significantly improved by about 171 and 124%, respectively, compared with neat chitosan.
