Multiwalled carbon nanotubes in the form of bucky papers were modified using Ar/O(2) plasma and thereafter melt-mixed into polycarbonate. The effect of plasma modification on the nanotubes was followed by XPS, indicating the formation of carboxylic o

To increase the applicability of carbon nanotubes (CNTs) oxygen-containing functional groups were generated on their widely inert surface by using glow-discharge plasmas. CNT-sheets (bucky papers) produced from the powder-like raw material were used

Due to their hydrophobic nature, carbon nanotubes (CNT) as well as CNT sheets (bucky papers) made thereof are limited in their applications. We use glow discharge plasma treatments to generate functional groups like alcohol or carboxylic groups on CN

In conventional plasma polymerization processes, the bulk properties of the treated substrates are maintained whereas the surface properties are changed to the ones of the coating polymer. In contrast, materials with ultrathin non-closed layers and d

X-ray photoelectron spectroscopy (XPS, ESCA) is an ideal tool for identifying differences in surface chemistry. In the past, it has lacked the spatial resolution as well as the performance of elemental or even chemical state imaging, to be of signifi

Tailor-made surfaces of polymer materials are required, e.g. for the improvement of their printability or adhesion and for many applications concerning medical equipment or life science products. Polypropylene (PP) is one of the few common polymers w

The plasma-based surface modification of polymer materials with desirable bulk properties is a useful way to obtain polymers with tailor-made surface properties. This is necessary because the surface properties of most engineering polymers in use tod
