Zeta potential analysis of fillers dispersed in water. The surface of N550 and Printex carbon black exhibited an electron donor (basic) characteristics. The isoelectric point for semi-active black and conductive occurred at respectively pH=9,5, pH=10,5. On the other hand the FW200 carbon black showed electron acceptor (acidic) characteristics in whole pH measuring range. 

From the data in fig. 4 it follows that the highest improvement of tear resistance was achieved by the addition of FW200 and Printex carbon blacks. The high impact on this parameter was due to the complex structure of this fillers. From all carbon filled composites the highest tear resistance was achieved for Printex filled composite with the addition of cationic dispersing agent DDAB. 

So far LII has only been applied for aerosol processes without the consideration of particles dispersed in liquids. First, investigations were carried out with re-dispersed carbon blacks. Besides furnace blacks (Printex A, G, 25, 35, and 55), various gas carbon black particles (FW 18, Colour Black SI60 and S170, Printex U and U140) were also considered. The particles were suspended in different liquids and dispersed by ultrasonic excitation. The stability of the suspension was recorded by measuring the aggregate size distribution (diffusion diameter) with DLS. Moreover, this was done before and after the LII measurements in order to control the stability of the particle suspension. To achieve LII... 

Printex XE-2 with its very good conductivity possess a large specific surface area. Concentration series up to 20 mass % carbon black. 

Pebax 2533 SA 00 with Printex XE-2 and wax Matrix and filler as in 1, but with a wax. The dosage is in each case 20% (of the weight) of the carbon-black content. It should be noted that the additive component is incorporated at the expense of the matrix component. This system was intended to indicate what influence the additive has on viscosity or on the shape of the curves. Concentration series up to 20 mass % carbon-black.

In a laboratory kneading chamber polycarbonate (PC) of medium viscosity (e.g. Makrolon 2600, Bayer) is mixed with different amounts of highly structured carbon black (CB, e.g. Printex XE2 (Evonik), up to 10 wt% in steps of 1-2 wt%) at ca. 280°C with a suitable defined mixing rate tiU a homogeneous mixture is obtained (typically 5-15 min). The melt will be taken out of the mixing unit, cooled down, and flat plates of the composites are prepared by compression moulding at ca. 280°C between two planar steel plates by means of a heatable hydraulic press. To hinder sticking of the composite at the metal plates, the plates may be covered with a release film and a frame can be used as distance holder to control the sample thickness. 

Polyethylene monofilaments (48 tex) were coated with a conductive polymer composite based on dispersion of Printex L6 carbon black particles in Evoprene 007 solution, using chloroform as a solvent (Cochrane et al., 2007). Two-ply polyethylene filaments were coated with the polymer solution as described above. The two ends of the coated polyethylene filaments were additionally coated with silver paint in order to reduce contact resistance, and fine copper wire was attached to the two ends with the help of this paint. In this way, secure connections were realized. Sensor strucmral and geometrical parameters along with initial electrical resistance are shown in Table 14.1. 

As coating solution, a conductive polymer composite based on dispersion of carbon black particles (Printex L6) in polystyrene (PS) solution, using benzene as a solvent was chosen.

Electrical conductive properties of carbon black filled vulcanizates. To obtain electrically conductive composites the carbon black aggregates have to arrange themselves in continuous paths where the conductive elements are either in direct contact or can move electrons via hopping or tunneling mechanisms [10]. On presented SEM image of composite containing Printex and BMIMBF4 the conductive paths composed from filler particles can be noticed. 

Thermogravimetric analysis. From fig. 6 it follows that the addition of carbon black to the elastomer composite increased its thermal stability. This is due to the improved thermal conductivity of vulcanizate achieved by the addition of the filler. The mass decrement is lowest for polymer filled with carbon black with the highly branched structure (FW200, Printex). This phenomenon is probably caused by the higher graphicity level of this types of carbon black [6].

In 2002, Bron and his colleagues compared the activity of catalysts made by the adsorption of Fe phenanthroline on three different supports Vulcan (254 m /g), Printex (900 m /g), and Black Pearls (1,500 m /g) . The Fe loading was 1.14 wt% for the three carbon supports, and all catalysts were obtained after...
