METHOD OF PRODUCING ELECTRORHEOLOGICAL SUSPENSIONS |
摘要 |
FIELD: chemistry.SUBSTANCE: method involves selecting a dispersion phase of an electrorheological suspension based on polyimide nanoparticles by simulation. Simulation involves constructing and optimising the structure of various oligomers and constructing the initial nanoscopic model of the elementary volume of the electrorheological liquid. An electric field is simulated by two planes and all molecular systems are situated strictly in between. Further, polyimides are synthesised by single-step high-temperature polycondensation of diamines and dianhydrides of tetracarboxylic acids with acylation and polycyclisation steps in a high-boiling solvent. Experimental testing of electrorheological suspension based on the modified polyimides is then carried out.EFFECT: invention enables to obtain electrorheological suspensions with improved process, rheological properties and strong electrorheological response.12 cl, 10 dwg |
