Grafting of Polymers onto a Carbon Black Surface by the Trapping of Polymer Radicals
The grafting of polymers onto a carbon black surface based on the trapping of polymer radicals by polycondensed aromatic rings of the surface was investigated. It was found that polymer radicals formed by the thermal decomposition of azo-polymer, peroxy-polymer and 2,2,6,6-tetramethylpiperidinyl-1-oxy-terminated polymer are successfully captured by a carbon black surface to give the correspondi...
متن کاملGrafting the surface of carbon nanotubes and carbon black with the chemical properties of hyperbranched polyamines
Controlling the chemistry on the surface of new carbon materials is a key factor to widen the range of their applicability. In this paper we show a grafting methodology of polyalkylamines to the surface of carbon nanomaterials, in particular, carbon nanotubes and a carbon black. The aim of this work is to reach large degrees of covalent functionalization with hyperbranched polyethyleneimines (H...
متن کاملGrafting of alkoxyamine end-capped (co)polymers onto multi-walled carbon nanotubes
Multi-walled carbon nanotubes (MWNTs) have been successfully modified by polystyrene, poly( caprolactone), and their block copolymers by addition reaction of the alkoxyamine-terminated precursors. Polymer-modified MWNTs are easily dispersed in good solvents for the grafted polymer, such as toluene and THF. This observation has been confirmed by TEM analysis. The grafting ratio of polystyrene ch...
متن کاملMolecular Weight Profiles of Proanthocy Anidin Polymers
The MW profiles of proanthocyanidin polymers (condensed tannins) from 32 samples representing a wide range of plant tissues of many different species have been obtained by gel permeation chromatography of the peracetate derivatives. The tannins vary widely in MW, with Al. values for the peracetates in the range 1600-5500. The MW profiles vary greatly from those with narrow, rather smooth distri...
متن کاملPrediction of the adsorption capability onto activated carbon of liquid aliphatic alcohols using molecular fragments method
Quantitative structure-property relationship (QSPR) for estimating the adsorption of aliphatic alcohols onto activated carbon were developed using substructural molecular fragments (SMF) method. The adsorption capacity of activated carbon (gr/100grC) for 150 aliphatic alcohols onto activated carbon (AC) is studied under equilibrium conditions. Forward and backwards stepwise regression variable ...
