Abstract

Izgudrojums attiecas uz enerģētikas nozari, sevišķi uz polimērmateriālu fleksoelektriķiem. Piedāvātais materiāls satur vismaz divus slāņus ar atšķirīgu porainību, raupjumu, kohēzijas enerģiju vai pildvielu veidu un saturu, turklāt katrs slānis, kontaktējoties viens pret otru, iegūst pretējas zīmes triboelektrisku lādiņu. Tādējādi daudzslāņainā materiāla tilpumā, notiekot slāņu savstarpējai berzei, veidojas dipola momenti un materiālam tiek piešķirtas fleksoelektriskas īpašības. Izgudrojumam ir vairākas priekšrocības – lai materiālā iegūtu dipola momentus, to nav nepieciešams pakļaut elektriskajam laukam, nav nepieciešams izmantot sarežģītus materiālus un metodes, un materiāla fleksoelektriskās īpašības ir noturīgas laikā.The invention relates to the energy sector, in particular to flexoelectrics of polymeric materials. The proposed material contains at least two layers with different porosity, roughness, cohesive energy or type and content of fillers, and each layer, in contact with each other, obtains a triboelectric charge of the opposite sign. Thus, in the volume of a multilayer material, dipole moments are formed during the friction between the layers and the material is given flexoelectric properties. The invention has several advantages - in order to obtain dipole moments in the material, it is not necessary to subject it to an electric field, it is not necessary to use complex materials and methods, and the flexoelectric properties of the material are stable over time.
