Аннотация

Subjects of research: the basic object of research is silk fibroin and wool keratin. For comparative experiences is chosen copolymer of acrilonytrilc. As the solvents the systems 2,5 M LiCl-DMFA, 2,5 M NaOH-water and 7,7 M NaCNS-watcr arc used. Purpose of work: consists in revealing laws of dcformational and orientational structure formation of fibroin and keratin at the non-newton stream of solutions and ions electrodialysis also definition of clcctroconductivity characteristics of received gels and besieged samples, containing residual ions. Method of research: rheooptimetry, birefringence, dispersion optical rotation, polarization ultramicroscope, viscosimetry, potentiometry, electrodialysis, ampermetry. The results obtained and their novelty': the features of education of solutions of fibroin and keratin in the ion containing the solvents are revealed and the critical parameters for a choice of a biopolymeric solution allowing to realize non-newton stream and ions electrodialysis arc established; representing structural organizations and interactions of electrodialysis for the first time arc found out the hysteresis effects at non-newton stream of solutions generated in the shift and longitudinal fields; opportunities of dcformational and orientational structure formation of fibroin and keratin for the first time are revealed at the non-newton stream of solutions with intensive removal of ions by means of electrodialysis; the conditions of reception gels and besieged samples of fibrillar proteins with high degrees of the factor of orientation of circuits and small quantity of residual ions determined; Arc determined of electroconductivity characteristics of received gels and besieged of fibrillar proteins depending on a degree of ordering macromolecules and contents of ions in samples; the installations rheooptimetry, complemented with electrodialysis for the investigations of structure formation arc assembled at the non-newton stream in conditions of intensive removal of ions. Practical value: revealed of dcformational and orientational of behaviour of of fibroin and keratin and also them hysteresis effects in the non-newton stream have the important meaning in development of fundamental representations about dynamics ordered structure formation of fibrillar proteins from solutions; the revealed laws of education of solutions, gels and besieged samples of fibroin and keratin at the presence of ions of salts and alkalis, and also them electroconductivity characteristics can be useful to development of scientific principles of processing fibrous wastes of silk and wool with reception of biomaterials with specific physical properties; the specially assembled experimental by generation non-newton stream and ions electrodialysis represent the large interest for research ordered structure formation of biopolymers with regulation of the contents of ions, and also for reception gels and besieged samples with electroconductivity properties on their basis. Field of application: dynamics high ordered structure formation of fibrillar proteins in a flow; clcctrophysics polymeric gels and compositions; ions electrodialysis; processing of natural polymers; polarization optics and rheology.
