Polymeric Materials,st example (but not a simple material) is polyethylene, which is derived from ethylene (CH.=CH.), in which the carbon atoms share electrons with two other hydrogen and carbon atoms: -CH.(CH.-CH.).CH.-, where . indicates the number of repeat units.

Structure-Property Relationships of Biological Materials,erials from artificial replacements. First, most biological materials are continuously bathed with a solution of water. Exceptions are the specialized surface layers of skin, hair, nails, hooves, and the enamel of teeth. Second, most biological materials can be considered as composites.

Soft Tissue Replacement I: Sutures, Skin, and Maxillofacial Implants,ed to match the physical and chemical properties of soft tissues. Polymers can be made into various physical forms such as liquid for filling spaces, fibers for suture materials, films for catheter balloons, knitted fabrics for blood vessel prostheses, and solid forms for cosmetic and weight-bearing applications.

Soft Tissue Replacement II: Blood Interfacing Implants,ney and heart-lung machine) and tubes and catheters for the transport of blood; and (2) long-term . implants such as vascular implants and implantable artificial organs. Although pacemakers for the heart are not interfaced with blood they are considered here because these devices help to circulate blood throughout the body.

Hard Tissue Replacement II: Joints and Teeth,ted dynamics of movement. In addition, the massive nature of totally replacing such joints as the knee and elbow near the skin also renders the possibility of infection greater. More important, if the replacement fails for any reason it is harder to replace the joint a second time because a large portion of the natural tissue has been destroyed.

Such an arrangement is called the metallic bond, to distinguish it from the covalent bond, in which electrons are shared between one another (Fig. 4–1).
