This presentation features the current state of research with respect to wetting and friction of elastomers. Plasma and varnished elastomer composites have been characterized by different wetting methods and friction investigations. Furthermore, it has been shown that the use of graphene-like filler...

Plastic is a product that has a wide range of applications, but the product also has a disadvantage - it is not degradable. It can be recycled and used for new purposes. The presentation includes the following aspects: typical applications of polymers, bioplastics, biodegradation, biorefining, bio-b...

Surface and interface phenomena play a very important role in many technical processes, including bonding and coating processes, surface printing, friction and wear behavior. A well-known natural surface phenomenon is the lotus effect, which can be attributed to the surface microstructure and hydrop...

Hybrid SBR composites have been compounded containing graphene nano-platelets in order to improve technical elastomer performance and to reduce the energy dissipation during frictional processes. It is still unclear how to manage a satisfactory exfoliation and inclusion in a rubber matrix. Therefore...

This article features the current state of research with respect to plasma and varnished elastomer composites, which have been characterized by the sessile drop and the modified Wilhelmy balance technique. The sessile drop measurement is well suited to assess smooth and plasma modified surfaces of e...

The physical performance of elastomer composites based on graphene nanoplatelets (GNPs) was investigated regarding the mechanical and fracture mechanical properties, viscoelastic and dielectric responses, and friction, wear and gas permeation properties. Static gas-adsorption measurements at very lo...

Magnetic elastomer composites based on SBR and NR have been compounded and characterized in order to observe the potential changes in mechanical properties in the presence of an external magnetic field. Micron-sized carbonyl iron and manganese zinc ferrite particles of a variety of sizes as well as ...

Various experiments have been performed to show the reduction of friction on smooth and rigid surfaces by tribometric methods. Varnished elastomers of EPDM and SBR have been investigated with respect to their friction properties on model substrates of steel, car glass and varnished sheets. It is dem...

Various experiments have been carried out to characterize smooth and rough varnished SBR composites. The composition of the coated elastomers was analyzed by ATR-IR and SEM-EDX. The topography and coating thickness were determined by SEM, white light interferometry and digital microscopy. Dynamic wa...

An advanced method of describing the impact of roughness on contact angles of different rough and varnished elastomers is presented here. The composition of coated elastomers was analysed by ATR-IR and SEM-EDX. The topography and coating thickness were examined by SEM and digital microscopy. Dynamic...
