Abstract

Composite nanocoatings on the surface of a titanium electrode are obtained by electrochemical reduction of macroions and fibroin nanoparticles in the presence of tricalcium phosphate. Based on the measurements, the dependence of the reduced viscosity (hуд/C) on C was constructed according to the Huggins formula hуд/C = [h] + k[h]2C (where k is a constant). For FB1 and [h] = 75 ml/g the intrinsic viscosity value [h] = 118 ml/g was found by means of С ® 0 extrazolation. The molecular masses М = 295000 for FB1 and M = 175000 for FB2 was calculated, respectively, as stated by Mark-Kuhn-Houwink equation М » ([h]/1,23*10-3)1/0,91. The studies were carried out on a specially assembled electrolysis unit using as a solvent HCOOH: Н2О (50: 50) under the influence of a direct current of 2-8 mA in a temperature range of 25-50°C. within 0.5 - 10 hours. The thickness of the nanocoatings in the range of 50 - 350 nm was controlled by changing the electrolysis time in the range of 0.5 - 10 hours. Furthermore, we have shown that the obtained samples of composite nanocoating FB are characterized by stability in the process of sterilization in ethanol at 60°C, as well as in salt-containing.
