  1. Dirty Half Dozen Stephanie Billiter, Karl Brunder, Paul Fisher, Jamie Shoup, Mike B, Jie Li

  2. Carbon Fibers • Popular for high flexibility, high tensile strength, low weight and ability to withstand high temperatures • Polymers of different molecular weight are being researched • Believe that higher molecular weight polymers produce stronger fibers.

  3. Reverse Osmosis • Polymer membrane used for desalination of water • Converts industrial waste into fresh water • Separation applications

  4. Green Tech • Plastics made from natural plant sources • Fully biodegradable • High fracture stress and High Young’s Modulus • Mixture of Soy protein concentrate (SPC) with micro-fibrillated cellulose (MFC).

  5. Stress and Young’s Modulus Graphs Figure 1: (a) stress vsgellan content curve showing fracture point of polymer. (b) Young’s modulus vsgellan content showing stiffness of polymer.

  6. Drug Delivery • Micro / nanoparticles • Scaffolds • Mechanical Support • Porous • Foaming / salt leaching • In vivo degradation • Hydrolysis of polyester bonds • Tunable degradation rate based on molecular weight, monomer ratios, end caps, pH, temp, etc • Biocompatible • Natural degradation products • Bioactive • Functionalized side groups • Functional monomers upon degradation J Contr Release 153 (2011), 133-140 ProcNatlAcad Sciences USA 108 (2011) 67-72
