“…[7] The observed process of hydrophilization of the TM surface on exposure to a gas-discharge is related to the formation of functional, in particular carboxylic, groups. [5] The appearance of COOH groups can be explained by the oxidation of the end groups formed at the break chemical bonds due to the active plasma particles effect.…”

“…[5] It has been shown that the gas-discharge etching of TM in the plasma causes of both increase in the pore diameter [6] and decrease in the a mass part of the low-molecular products in the membrane.

“…So, using carbohydrates (cyclohexane, for example) as a plasma-forming gas, a thin polymer chemically stable film is formed on the surface exposed to plasma of not possessing functional groups. [5] This provides a way for producing hydrophobic composite membranes possessing a chemical strength. While depositing the polymer film from the discharge to hexamethyldisilazane, the membranes having bactericide properties are formed.…”

“…While depositing the polymer film from the discharge to hexamethyldisilazane, the membranes having bactericide properties are formed. [5] A positive or negative charge appearing due to the introduction of the functional groups is one more thing allowing one to regulate the membrane characteristics. For instance, the use of dimethylaniline [9] or acrylic acid [10] as a plasma-forming gas serves as a basis for creation of hydrophilic composite membranes.…”

“…Depending on the duration of the plasma treatment, one can obtain membranes for microfiltration, ultrafiltration, and reverse osmosis. [5] In the last case, a thin semipermeable layer that fully covers the pores is deposited on the membrane surface. The possibility of adjusting the thickness of the polymerized layer and the wide range of organic compounds for producing the membranes of this type make this method very promising.…”

The effect of plasma treatment on the properties of poly(ethylene terephthalate) track membranes has been investigated. The influence of plasma treatment conditions and composition of plasma‐forming gas on basic membrane characteristics–pore size and shape, wettability, hydrodynamic, and electrochemical properties–were studied. It is shown that the plasma treatment of membranes can significantly improve their performance characteristics and give them a lot of useful properties.

The large interest in nanostructures results from their numerous potential applications in various areas such as materials and biomedical sciences, electronics, optics, magnetism, energy storage, and electrochemistry. Ultrasmall building blocks have been found to exhibit a broad range of enhanced mechanical, optical, magnetic, and electronic properties compared to coarser-grained matter of the same chemical composition. In this paper various template techniques suitable for nanotechnology applications with emphasis on characterization of created arrays of tailored nanomaterials have been reviewed. These methods involve the fabrication of the desired material within the pores or channels of a nanoporous template. Track-etch membranes, porous alumina, and other nanoporous structures have been characterized as templates. They have been used to prepare nanometer-sized fibrils, rods, and tubules of conductive polymers, metals, semiconductors, carbons, and other solid matter. Electrochemical and electroless depositions, chemical polymerization, sol-gel deposition, and chemical vapour deposition have been presented as major template synthetic strategies. In particular, the template-based synthesis of carbon nanotubes has been demonstrated as this is the most promising class of new carbon-based materials for electronic and optic nanodevices as well as reinforcement nanocomposites. PACS: 61.46.+w; 61.48.+c; 61.82.RxIn 1959 Richard Feynman, the future Nobel Laureate, suggested in his famous lecture, entitled "There's Plenty of Room at the Bottom", a variety of tests that might be achieved at very small scales. Three decades later Feynman's vision has become the greatest scientific frontier of the century. It opened a new field of "Nanostructures" having dimensions of about 10 to 1000 Å, a size that is small by engineering standards, common by biological standards, and large to chemists.The central thesis of nanotechnology is that almost any chemically stable structure that can be specified can actually be built. Nature has plenty of proof that nanotechnology works, from the liposomes in cells that manufacture proteins atom by atom, to the chloroplasts of plants that turn sunlight, carbon dioxide, and water into copies of themselves. Since biological machines exist, and work, and since biology follows the same laws of physics and chemistry applied by engineers, there's no question the nanostructural machines will work. Scientists have to figure out, however, how to build them.Of particular significance is the size dependence of many properties in nanomaterials, for example, an enhancement in the strength and hardness of solids; the possibility of modifications of their electrical properties by control of the arrangement within the constituent nanoclusters and of their assembly; the control of chemical reactivity by the attachment of functional side-groups; the control of optical properties by variation of the size and microstructure of the nanoclusters; the possibility of creating nanostructures of metastable phases with no...
