Porous matrixes based on ion-irradiated polymer as templates for synthesis of nanowires
Irradiation with swift heavy ions is usually used for production of track membranes
(nuclear filters). These membranes traditionally used as filters for fine filtration
in medicine and biology.
Another application is matrixes for so called matrix synthesis. The idea of this
technique is to fill pores by any desired material- metal,polymer, semiconductor and so
on.
This work is devoted to formation of membrane for template synthesis, to investigation
of filling process and to study some properties of obtained structures.
It was found that filtration track membranes are not the best material for template
synthesis –another type of matrixes are needed- with different pores profiles and parallel
pores orientation These parameters could be obtained during irradiation. Different
types of etching gave possibility to vary by will the shape of the pores and to obtain
pores with conical shape. The process of etching in the alkali solution in mixture of
water and alcohol was investigated.
The main part of the work devoted to fabrication of micro- and nanowires via electrodeposition.
Different types of metals-copper, silver, cobalt and nickel were used for
galvanic deposition of the pores. Two types of the processes- galvanostatic and potentiostatic
were investigated.
It was also demonstrated that obtained metallic nanowires could be used as the
substrates for deposition of the probe (biological molecules) in mass-spectrometer.
The application of such structures in non-linear optic was also described.
