Nano fibrous materials

With the purpose of increase in a specific surface and electroconductivity of GPSi the technology of gas-phase pyrolitic sedimentation of a layer carbon fibrous nanomaterial on a surface of macropores is developed [8]. Process of sedimentation carbon fibrous nanomaterial at catalytic decomposition of the ethanol steam proceeds strictly selectively, and the received material practically does not contain some soot. The nano-fibrous layer of carbon is homogeneously enough located on all surface of macropores (Fig. 8), thickness of a layer makes about 0,1-0,4 microns and depends basically on modes of sedimentation. The layer represents a mix nano-... 

XRD-results have shown that aluminium oxide was formed at 600-700 °C. It consists of nano-dimensional grains and have the y-structure providing the high reactivity of fibrous material. When fibres of aluminium oxide were heated to 900 °C, its crystal structure varied from y- to 0-phase, and above 1200 °C it changed to a-corundum. It is illustrated by the patterns in Fig. 1.

But PVC forms many composite materials with particulate and fibrous fillers. Cellulose fiber and newsprint recycled fiber are two common examples of fibrous materials. The list of powders is longer, including talc, mica, clay, wood flour, carbon black, glass beads, hydrotalcite, alumina trihydrate, polypyrrole, and various nano-materials including nano-calcium carbonates. 

Abstract The use of two environmentally friendly technologies, the plasma and laser approaches, in treating the surface of textiles is discussed in this chapter. The surface of fibrous materials can be functionalized and structured on the nano- and micro-scales, and the results of the treatment of natural and synthetic fibres such as wool, cotton, polypropylene, polyester and polyamide which have been treated by different plasmas and lasers are detailed and are found to be similar to morphological modification of a textile surface using the ripple/roll-structure technique. 

The mechanical performance of electrospun nanofibers concerning nanocomposites can be discussed at different levels such as mechanical properties of single nanofibers, nano-fibrous self-products, and nanofiber reinforced composites as well. When designing composites it is crucial to know the mechanical parameters, behavior and damage process of the nanofibrous materials.

Several PPE-containing AB and ABA block copolymers have been made and investigated for their phase behavior, optical properties, and self-assembly [60-62]. Such AB block copolymers give well-developed morphologies, fibrous self-assembled nano tubes (Figure 6.1). Surprisingly, these materials do not form the interpenetrated networks observed by Hillmyer for polylactide/polystyrene (PS) blocks [63].

A decade ago, it was believed that the most common polymer composites, comprising about 30% glass fibers, would replace the nanocomposites having as reinforcement only 2 to 5 wt% nano-sized minerals. Unfortunately, this expectation turned out to be false [5]. For this reason, researchers started to look for alternative ways to replace classical glass fibers with natural, biodegradable materials, mostly with fibrous structures. The potential of this approach is demonstrated in [6],...
