  1. Emerging Polymers Team: DiPole Moment Luis Whitworth, Barry Herndon, ________

  2. Proton Exchange Membrane (PEM) Fuel Cells Materials Needs Trends Renewable energy is becoming increasingly important. Development of reliable, efficient fuel cell can be used in a wide range of applications Economically viable and environmentally beneficial. • These fuel cells use thin polymer membranes as the electrolyte that must conduct protons across membrane but not electrons and seal in gasses. Must also be resistant to conditions on both cathode and anode side of cell. • Operate at 80 degrees C (compared to 1000 degrees C of others) and lighter to use.

  3. OLED/PLED • Easy to functionalize • Delocalized pi electrons • External voltage • Ink-jet printing • Renewable • Cheaper

  4. BPA Free Plastics • BPA – BisPhenol A (estrogen mimic) • 100% BPA Free • Uses a new copolymer developed by Eastman Chemical • Bottle is made from Tritan

  5. Tritan • Eastman TritanEX401 copolyester • 100% BPA free, highly durable, chemical and heat resistant • Used by Camelpak in their better water bottles • Also used in baby bottles, microwavable plastic containers, kitchen utensils

  6. Lexan SLX is an amorphous polycarbonate copolymer with PC segments alternating with ITR segments. ITR (isophthalateterephthalate resorcinol) First the uv will penetrate the material until enough energy is stored in the material to transform the polymer configuration. The ITR transforms to hydroxybenzophenones which will absorb the uv radiation It was been lab test to hold 95% glossy finish for 10 years Polymer Uses Sunlight To Arm Itself Against UV Damage
