Dirty Half Dozen

Stephanie Billiter, Karl Brunder, Paul Fisher, Jamie Shoup, Mike B, Jie Li


Carbon fibers

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.


Reverse osmosis

Reverse Osmosis

  • Polymer membrane used for desalination of water

  • Converts industrial waste into fresh water

  • Separation applications


Green tech

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).
