Abstract

This paper presents the developed probabilistic spatial model fragments of the structure of polyacrylonitrile fiber, the monomerization composition (condensing components of the polymer matrix), and “Polikon K” – “Polikon K1a” material. The dynamic contact angle of the investigated material was experimentally determined, and the work of adhesion (1.154 mJ/m2) and wetting (73.855 mJ/m2) of the surface material was calculated. The model of the structure of the “Polikon K1a” material indicates the most likely point of
interaction of copolymer polyacrylic fiber with reactive CH3– groups of the polymer matrix, namely, the interaction with the C≡N group, by breaking one bond and forming a methylene bridge. The size of the unit cell of the model was estimated: 10.6 × 10.3 × 9.7 Å. The dependence of the torsion angle near the methylene bridge on the concentration of water molecules was investigated.
