title: [Use of low-temperature plasma in the preparation of synthetic polymers for modification by collagen].
abstract: The physico mechanical properties of films, vascular prostheses and nets made of polyethylene terephthalate and polyethylene film treated with the low temperature plasma were investigated. The plasma was generated by glow discharge in air under the following conditions: gas pressure - , current - 0.4-0.6 A, time of treatment - 40-240 s. stated that the angles of wetting with water and collagen solution of films treated with plasma decreases considerably. Sharp decreasing of wetting angles is followed by quick rise of the between water and polymeric film, and also by the increasing of free surface energy. The increasing of the wettability does not change during the storing time. The breaking stress and extension of the films treated with plasma are the same or a little bit higher than those of the untreated ones. The collagen modified by radiation shows high adhesion to the polymeric materials treated with plasma. The value of this adhesion 6 x 10(5) mN/m for polyester film, is about 6 times higher than the value of adhesion obtained by other authors, if the polyester film was treated with air plasma generated by spark discharge method.
