Abstract
It is well known that at the present time two basic aspects of a material’s nano-objects sensitization should be considered. The first aspect relates to the change of the material’s basic physical-chemical properties when the concentration of the nanoobjects in the material’s body is varied. The second aspect is in regard to the modification of surface properties on the content of the nanoobjects in the material’s body. In the current paper the correlation between the concentration of the nanoobjects and wetting phenomena of the material’s surface is considered. Different experimental instruments and supporting models are presented with good coincidence.
Highlights
More and more nanotechnological aspects are considered, both from a fundamental point of view for expanding the material science knowledge, and from a practical point of view, due to the widespread use of the nanomaterials and devices based on them in general optoelectronics and biomedicine
To summarize the obtained results and proposed idea, one can present the following interesting aspects, which can extend our knowledge in the area of material science and which can be useful for future practical applications
There is a certain concentration range of the dopant, at which there is a variation in the configuration of the surface relief
Summary
More and more nanotechnological aspects are considered, both from a fundamental point of view for expanding the material science knowledge, and from a practical point of view, due to the widespread use of the nanomaterials and devices based on them in general optoelectronics and biomedicine. (Saint-Petersburg-Moscow, Russia), was used in order to establish the change of the wetting angle at the modified polymer surfaces, when the content of the nanoobjects in the model material’s body was varied. Considering some practical application, one can conclude that this surface relief can be useful for the display technique because it can be easy modified, for example, for the liquid crystal molecules orientation from the orthogonal to planar position (and back) and can be proposed, for comparison, in the TN- and MWVA-display technology This effect can be considered in polarizing optics in order to vary the transmittance of the parallel and orthogonal light components. This data reveals the dependence of the wetting angle of the water drops at the surface of thin-film PI matrix with the fullerene C70 concentrations varying of 0.1; 0.2; 0.5; and 1.0 wt.%
