Research activities conducted in the laboratory are aimed at receiving new carbon materials, such as graphene (graphite monolayer) and carbon nanotubes (CNT) as well as composite materials with different nonoparticles on their basis. The properties of these materials have been intensively studied around the world to understand their possible applications in modern electronics, including in flexible devices as well as sensors sensitive to being pressed and different gases. They are also being studied as the components of materials for lithium-ion baterries and LEDs.
The structure and properties of carbon nanomaterials can significantly differ depending on the synthesis parameters. For CNT and graphene important structural parameters are a number of layers, defect structure and the presence of dopant atomsamong others. Different types of materials are necessary for different kinds of applications, that is why to receive carbon materials with a specific given structure is a necessary task to be dealt with by the joint laboratory.
The laboratory results:
- Researching multilayerd graphene structures and the modofication of their surface with fluorine atoms made it possible to create materials that can act as ammonia.sensors.
- New physical data about the critical melting point in metals in the system Pd-Rh at 820°C, synthesized by means of thermal decomposition of coordination conjunctions have been obtained. The process of receiving an alloy Cu-Pd using CVD method from the precursor of the compound PdL2 at a reduced pressing and in the temperature range of 200–350°C has been demonstrated for the first time.
- Alkyloxi- and fluoroalkyl-substituted zinc phthalocyanine films as well as hybrid materials on the basis of liquid crystal phthalocyanine metals and carbon nanotube have been received and described. Optical response of films of hybrid phthalocyanine materials to amine vapor content in the air and benzopyrene in water has been studied, thus openinig new possibilities for using these films as sensors.
- Metal nanoparticles taking part in cathalysis of new carbon and hybrid materials have been received and studied.
- For the first time Ni and Co fixed composition polymolibdates on an inert carrier were used as precursors for cathalitic growth of low-layered carbon nanotubes; the mechanism of their formation was suggested.
Carbon nanotube and nanodiamond hybrid materials with fluorescent emission in a weak field as well as becoming an effective cathalist to obtain hydrogen in the process of formylic acid cleverage have been received.
