ABSTRACT
With the use of yttrium and bismuth ceramics’ powders (Y 1 Ba 2 Cu 3 O 6.97 andBi 2 aSr 2 Ca 2 Cu 2 O 8), on the basis of super-high molecular polyethylene binder, current-carrying polymer-ceramic nanocomposites are obtained. It is shown that the implementation of the proximity effect between the ceramics’ grains leads to obtaining superconducting polymer-ceramic nanocomposites with a transport current. Additives of silver and aluminum nano-scale powders cause significant increase of current density, and the application of acoustic fields during the formation of samples allows to further increase the density to ∼ 4 - 103 A cm - 2 $ \sim 4 - 103{\text{A}}\,{\text{cm}}^{ - 2} $ https://s3-euw1-ap-pe-df-pch-content-public-p.s3.eu-west-1.amazonaws.com/9781315365985/93067212-2742-4adb-9a79-69b21685310d/content/inline-math2.tif"/> . Physical and mechanical properties of current-carrying polymer-ceramic nanocomposites have been investigated and it is shown that nano-sized aluminum additives increase the breaking strength and the elasticity modulus of the samples. The morphological features of currentcarrying polymer-ceramic nano-composites’ interphase layer on the basis of various binders (polymethylmethacrylate, polystyrene, super-high molecular polyethylene and isotactic polypropylene) have been studied.
