Physico-mathematical modeling and informational technologies| Summary: | The influence of carbon nanotubes (CNТ) on enthalpy relaxation kinetics of polymethylmetacrylate(PMMA) is studied by the method of differential scanning calorimetry. The improved phenomenologicmodel for description of the structural relaxation of amorphous polymers in the glassingarea is offered. The kinetic parameters of enthalpy relaxation for neat PMMA and nanocompositeswhich contained from 0,2 to 2 % carbon nanotubes were got from calculations. The fact of theinfinite cluster formation were set from the changes of kinetic relaxation parameters. The featuresof polymeric composites’ structure influence on their thermophysical properties are studied. |
