22-2-96 CONDUCTING POLYMERS By Colin Pratt INTRODUCTION Until about 30 years ago all carbon based polymers were rigidly regarded as insulators. The idea that plastics could be made to conduct electricity would have been considered to be absurd. Indeed‚ plastics have been extensively used by the electronics industry because of this very property. They were utilized as inactive packaging and insulating material. This very narrow perspective is rapidly changing as a new class of polymer known

calculated to be 176.3 while the accepted value was found to be 183.5. The identity of the unknown amino acid was established to be glutamic acid‚ hydrochloride. Introduction Amino acids are simple monomers which are strung together to form polymers (also called proteins). These monomers are characterized by the general structure shown in figure 1. Fig. 1 Although the general structure of all amino acids follows figure 1‚ the presence of a zwitterion is made possible due to the basic

several conjoined sugars). Synthesizing starch enables the plant to stockpile surplus glucose‚ and since glucose is a major cellular fuel‚ starch represents stored energy. The sugar can later be withdrawn by hydrolysis‚ which breaks the bonds between monomers. Animals‚ in turn‚ have enzymes that can hydrolyze plant starch‚ making glucose available as a nutrient for cells. Cellulose‚ on the other hand‚ is used in plant cells for structural support. For example‚ wood is a strong building material that
