Electrochemical preparation of metal microstructures on large areas of etched ion track membranes
Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 1999A microgalvanic method for metal filling of etched ion tracks in organic foils on large areas is described. The method and the used galvanic cell permit the deposition of stable standing individual metal whiskers with high aspect ratio and a density of 105–108 per cm2 on an area of 12.5 cm2.

Chemical Synthesis of AgCl Microstructures Using Etched Ion Track Polycarbonate Membranes
Synthesis and Reactivity in Inorganic, Metal-Organic, and Nano-Metal Chemistry, 2012Large-scale synthesis of uniform AgCl microstructures within the pores of polycarbonate track etched membrane is reported. Morphological study of AgCl microstructures was done using scanning electron microscopy. X-ray diffraction studies show the crystalline structure of AgCl microstructures.

MEASUREMENT OF AVERAGE ETCHED PORE RADIUS IN ION TRACK MEMBRANES THROUGH CONDUCTOMETRIC TECHNIQUE
Modern Physics Letters B, 2008In the present work, average pore radius in etched PC and PET membranes, exposed to various heavy ions, has been determined using the conductometric technique. The average pore radius, measured directly through optical microscope, has been found to be higher (15%) than the values determined using the conductometric method.

The effect of surfactants on chemical development of ion tracks in polymers has been studied. It has been shown that surface-active agents added to an alkaline etching solution adsorb on the polymer surface at the pore entrances. This reduces the etch rate, which leads to the formation of pores tapered toward the surface.

Making porous membranes by chemical etching of heavy-ion tracks in β-PVDF films
Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 2005Abstract Production of porous membranes using heavy ion bombardment and subsequent chemical etching of poly(vinylidene difluoride) (PVDF) films has been reported several years ago. However, porous membranes with pore diameter in the nanometer scale requires a better understanding of the chemical etching mechanism.

Modifications induced in PVDF films by irradiation with energetic heavy ion beam have been determined by electron spin resonance (ESR). We have studied the evolution of radical density under different measurements atmospheres (vacuum and air) as function of temperature, ageing time and annealing.
