http://en.wikipedia.org/wiki/Conductive_polymers

Extractions: From Wikipedia, the free encyclopedia (Redirected from Conductive polymers Jump to: navigation search Conductive polymers or more precisely intrinsically conducting polymers (ICPs) are organic polymers that conduct electricity Such compounds may have metallic conductivity or be semiconductors . The biggest advantage of conductive polymers is their processability. Conductive polymers are also plastics , which are organic polymers. Therefore, they can combine the mechanical properties (flexibility, toughness, malleability, elasticity , etc.) of plastics with high electrical conductivity. These properties can be fine-tuned using the methods of organic synthesis In traditional polymers such as polyethylenes , the valence electrons are bound in sp hybridized covalent bonds . Such "sigma-bonding electrons" have low mobility and do not contribute to the electrical conductivity of the material. The situation is completely different in conjugated materials. Conducting polymers have backbones of contiguous sp

What are photopolymers? Photopolymers are imaging compositions based on polymers/oligomers/monomers which can be selectively polymerized and/or crosslinked upon imagewise exposure by light radiation such as ultra-violet light. For final use, they are made into different forms including film/sheet, liquid, solution etc. which find outlets in printing plates, photoresists, stereolithography and imaging. A popular use of liquid photopolymers is in making of rubber stamps. Photoresists are used to make integrated circuits, flat panel displays, printed circuits, chemically milled parts, MEMS (microelectromechanical systems) etc. Similar liquid compositions can also be used for non-imaging applications such as adhesives, coatings and inks. A photopolymer product can be applied as a very thin coating as in liquid photoresists or formed into a large model as in a stereolithographic equipment.

Provides information about the self healing polymers research group at the University of Illinois. Contains publications in full text (PDFs) and a gallery including photos, animations and videos.
http://www.autonomic.uiuc.edu/

Extractions: In nature, damage to an organism elicits a healing response. We apply this concept to synthetic material design and have developed a self-healing polymer. Tiny capsules containing a healing agent are embedded in the polymer. When the material is damaged, the capsules rupture and release the healing agent, which repairs the cracks.

http://library.thinkquest.org/3659/orgchem/polymers.html

Extractions: Almost all of the molecules we have studied so far have been relatively small with low molecular masses. But in nature and the world of synthetics, there are many substances with molecular masses in the thousands and hundred thousands containing hundreds or thousands of atoms. These molecules are called macromolecules Some macromolecules have more structural order than others. A polymer is a macromolecule in which all of the molecules have a small characteristic structural feature that repeats itself again and again. For example, here is a molecule of polyethylene: etc.-CH CH -CH CH -CH CH -CH CH -CH CH -etc. The strucutre has one structural unit, or monomer , that occurs repeatedlyethylene (ethene), CH CH . The structure of the polymer can therefore be represented by: -(CH CH n Where n can be several thousand. Polymers therefore do no consist of molecules identical in size but identical in kind.

Protein polymer formed from amino acid monomers. Image credit: U.S. Department of Energy Genome Programs Polymers are large molecules composed of many similar smaller molecules linked together. The individual smaller molecules are called monomers. When small organic molecules are joined together, giant molecules are produced. These giant molecules are known as macromolecules. Generally speaking, all macromolecules are produced from a small set of about 50 monomers. Different macromolecules vary because of the arrangement of these monomers. By varying the sequence, an incredibly large variety of macromolecules can be produced. While polymers are responsible for the molecular "uniqueness" of an organism, the common monomers mentioned above are nearly universal.
