Polymer Electrolytes: Fundamentals and Applications

Polymer electrolytes are electrolytic fabrics which are common in batteries, gas cells and different purposes comparable to supercapacitors, photoelectrochemical and electrochromic devices. Polymer Electrolytes: basics and functions offers a big evaluation of this classification of ionic conductors, their homes and functions.

Practical Guide to the Assessment of the Useful Life of Rubbers

The article of this book is to supply sensible counsel on assessing the beneficial carrier lifetime of rubbers. It describes try methods and extrapolation ideas including the inherent boundaries and difficulties. This advisor seeks to be complete yet concentrates at the most typical environmental results inflicting degradation and an important mechanical houses of rubbers.

Fundamentals and Advances in Knitting Technology

This e-book appears to be like on the historical past of knitting and the way the method has advanced to the current. Chapters talk about the rules eager about varieties of knitting machines and the different sorts of loops and knitted buildings. the writer additionally examines the technological know-how and caliber facets of knitting, calculations with regards to knitting and the mechanics of knitting.

Sample text

The polymers are also bonded together by strong intermolecular forces. As a result, polyester fibers have high mechanical strength, toughness and abrasion resistance, as well as high elongation and elastic recovery. However, polyester fibers require higher forces to elongate as compared to nylon fibers. They also have higher resistance to heat and chemicals (including acids and oxidizing agents) than nylon fibers. Its hydrophobic nature and low moisture absorption can cause static buildup. An inert material, polyester fibers have found applications in medical and healthcare products for internal uses, such as nonabsorbable suture, vascular grafts and ligament prostheses.

More importantly, it is the only approach capable of producing filaments from a large variety of natural and synthetic polymers. For this reason, electrospun nanofibers will be the focus of the rest of this chapter. 2. BIOPOLYMERS USED FOR NANOFIBERS A wide range of biopolymers, both natural and synthetic, have successfully been electrospun into nanofibers. , without having to be mechanically removed; see Chapter 5). Some of the widely used biopolymers will be discussed in this section. 1. , cellulose and its derivatives, chitin/chitosan, and hyaluronic acid).

6. α-helix keratin (polypeptide) polymer. 7. The pleated β-sheet structure. mer chains to pack so tightly that the silk fiber is high in terms of its crystalline regions (70–75%), and low in amorphous regions (25–30%). The surface of silk fibers is covered with a layer of sericin, also referred to as silk gum. Most of the gum on the fiber surface is removed to allow further textile processing procedures. Silk is a hydrophilic fiber. , acceptance of an artificial implant by the surrounding tissues and by the body as a whole.
