The present paper reviews recent patents on polymer-inorganic particle blends with reference to silver particu- late films on softened polymer composites of polystyrene (PS)/ poly (2-vinyl pyridine) (P2VP) and PS/ poly (4- vinylpyridine) (P4VP) deposited at a rate of 0.4 nm/s held at a temperature of 457 K in vacuum of 8� 10 -6 Torr by evapora- tion. There has been continuous development in the field of polymer-inorganic nano particle blends. Polymer-inorganic particle blends are incorporated into structures involving interfaces with additional materials can be used for forming de- sirable devices. Polymer blends with a vast variety of characteristics, architectures with properties that are often not accessible with individual components are prepared. A method is used to form metal nanoparticles having a desired shape and size by combining in a single solution, solvent, metal ions and copolymers under conditions such that metal nanopar- ticles are formed. Nanoparticles layers can be distributed on a substrate using various methods. Blending of insulating polymers with metal particle provides an insulating cover and cost reduction. Various methods are used to design nano- particle on a dielectric substrate for desired applications like charge storage in electronic devices, system and optical sen- sors.

We suggest a method of growing silicon carbide crystal layers on carbon foil. The material is produced by moving a carbon foil tape at a speed up to 2.5 m/min in dynamic vacuum against a graphite capillary feeder that contains molten silicon. As a result of various chemical vapor reactions, SiC crystals grow at a speed up to 1.5 mm/s. The crystals and the foil form a composite material with semiconducting properties. In this article, we have discussed relevant patents.

The patent review is devoted to consideration and analysis of several methods of producing materials and arti- cles based on carbon, silicon and silicon carbide. Common to these methods are: (i) the use of carbon as initial material for growth of Si or SiC, (ii) the use of single crystal Si as substrate for synthesis of nanocrystalline carbon, (iii) execution of the processes at low pressure of the reagents and their strong chemical interaction. The methods considered do not im- ply preliminary grinding of initial components, their sintering, hot pressing, etc. In fact, this group of methods and rele- vant materials hold a peculiar position between crystal growth and techniques of producing composite materials. The analysis made allows formulating the following debatable conclusions: (a) non-porous SiC-Si composites forming upon direct contact of molten silicon with fibrous carbons can be used as resistive material in diverse technical applications; (b) in spite of the wide variety of methods of growing solar grade silicon sheets, only self-supported methods can be regarded as viable; the optimal silicon sheet structure includes parallel twin boundaries, the average dislocation density should not exceed 10 5 cm -2 ; (c) deep purification of bulk graphite is possible under the conditions of cycling inlet/outlet of halogen agents; the process realized can be environmentally safe even when using Freon; (d) carbon nanoclusters produced by chemical vapor deposition can be considered as components for creation of drug delivery preparations.
该专利审查致力于考虑和分析几种以碳、硅和碳化硅为基础的材料和制品的生产方法。这些方法的共同点是:(i)使用碳作为硅或碳化硅生长的初始材料，(ii)使用单晶硅作为纳米晶碳合成的衬底，(iii)在试剂的低压和它们强烈的化学相互作用下执行过程。所考虑的方法不包括初始部件的初步研磨、烧结、热压等。事实上，这组方法和相关材料在晶体生长和复合材料生产技术之间具有特殊的地位。通过分析可以得出以下有争议的结论:(a)熔融硅与纤维碳直接接触形成的无孔SiC-Si复合材料可以用作各种技术应用中的电阻材料;(b)尽管种植太阳能级硅片的方法多种多样，但只有自给自足的方法才能被认为是可行的;最佳硅片结构包括平行孪晶界，平均位错密度不超过10 5 cm -2;(c)在卤素剂循环进出的条件下，块状石墨的深度净化是可能的;即使使用氟利昂，所实现的过程也可以对环境安全;(d)通过化学气相沉积产生的碳纳米团簇可以被认为是制造给药制剂的成分。
