Kinetics of polymer nucleation on active centers

We have numerically solved kinetic equations describing formation of nuclei on active centers to determine the total number of nuclei, nucleation rate and the number densities of nuclei near critical size. Results of our model were compared ...

Nucleation on polymer nanofibers and their controllable conversion to protective layers: preliminary theoretical study

material on which technically interesting nanoclusters are heterogeneously nucleated. The basic thermodynamics of heterogeneous nucleation on nanofibers is considered. The extreme curvatureof nanofibers manifests ...

Stimulated nucleation on polymer nanofibres

We present preliminary results of our research on heterogeneous nucleation on polymer-based nonwoven nanofibres. It is shown essential difference between standard nucleation theory and theoretical description of clusters fo...

Effect of nucleation agents on mechanical properties of polypropylene

This contribution deals with the effect of nucleation agents on mechanical properties of isotactic polypropylene (iPP). Tested material was modified using alpha and betha nucleation agents. Tensile tests, 1H-NMR an...

Statistics of heterogeneous nucleation

We analyzed the possibility of occurrence of bimodal distribution function due to fluctuations of nucleation rate. It appears that heterogeneous nucleation always produces unimodal distribution function if number of active ...
