Abstract
The change of the molecular organization in the liquid crystal (5CB)-aerosol system under the influence of electric field is investigated with the use of IR spectroscopy methods. It is shown that aerosol A-300 addition (10 weight %) to 5CB leads to forming weak hydrogen bonds between the aerosol hydroxyl groups and the (pi) -electrons of benzene rings of 5CB (Si-O- H...(pi) ). Under the influence of electric field (U equals 60 V, f equals 2 kHz) these bonds undergo a rearrangement, the 5CB molecules in the aerosol pores align along a direction of the electric field and then form the new network of hydrogen bonds. In the case of the aerosol modified by the polymethylsyloxane the formation of new hydrogen bonds does not take place and in the electric field the 5CB molecules are easily oriented along the field direction.
