Equipment

OLEM is equipped with advanced equipment for mechanical, thermal and rheological characterizations of materials, liquids and solids. Study of polymer nanomaterials, ultrafine films, soft and hard coatings, ceramics and metals for mechatronics, micro and nanoelectronics applications.


OLEM provides:

Surface mechanical testing at nanoscale: nanoindentation, nanoscratch, nanotribology, adhesion of coatings to the substrate, nanoindentation of soft materials with the tip of Atom Force Microscopy.

Surface mechanical testing at microscale: microindentation, friction and wear, coefficient of friction.

Deformation and fracture tests: mechanical strength in tensile, bending, compression and torsion of fibers, films, folia, small samples and electronic details in thermo-chamber (20-170оС). Stretching of ultrafine films by "small punch test".

Rheology in shear and dynamic mode of wide spectra of materials: nanodispersions, polymers, oils, pastes, materials for food industry, cosmetics and pharmacy, dental materials.

Dynamic mechanical thermal analysis (DMTA) in torsion, in wide range of amplitudes and temperature (-80-600оC)

Thermal analysis (DSC and TGA) in air and nitrogen atmosphere.

Polymer nanocomposite processing - extrusion of filament for 3D printing (1.75 and 3 mm) .

Processing of nanodispersions with graphene, carbon nanotubes and other nanoparticles in liquid phases by high speed mixing and ultrasonic treatment.

Prototyping by FDM 3D printing.
