    Materials Sustainability Responsive Materials Responsive Peptide Block Copolymers polypeptide based block copolymers in solution One of the main research goals in the Savin group is to understand and control the assembly and responsiveness of polypeptide based block copolymers in solution In general the behavior of polyelectrolytes in solution is not well understood in part due to their complexity Synthetic polypeptides in solution can be used as a model for synthetic polyelectrolytes due to the ability to control the charge charge interactions between ionizable units In addition by using polypeptides we can incorporate pH and T responsiveness into a material based in part on the secondary structure changes that occur within the peptide chain We can also dictate the geometry of specific interactions to induce folding and assembly into responsive hydrogels crosslinked core shell structures and multiply responsive or schizophrenic materials The use of polypeptides in these materials introduces an immense toolbox that allows for control over the specific structure property relationships that govern the resultant material Our principal analytical tools are dynamic light scattering and rheology although we invoke most polymer solution techniques We also rely heavily on microscopy TEM and AFM The PI has extensive experience in polymer characterization

    the Environment New concentration independent oil dispersants Novel Oil Dispersants The Deepwater Horizon oil spill demonstrated a key need for the development of environmentally friendly dispersants In collaboration with Lochhead and Morgan we are developing a novel oil dispersant that is derived from food products This formulation is able to sequester the oil while keeping the droplet at the air water interface so it can be broken down naturally or skimmed off the surface This new dispersant also does not allow the oil to redeposit onto sand and bird feathers In a separate project in collaboration with Grayson and Reed we are developing new concentration independent dispersants that will not allow sequestered oil to be released in the infinite dilution of the ocean Nanoparticle toxicity There is little that is known of the environmental impacts of nanoengineered materials at the end of the material life cycle In particular there is concern that leeching of nanoparticles into the ecosystem may be toxic to some organisms In collaboration with Griffitt and Morgan we attempt to determine how particle properties and or modifications affect toxicity in estuarine ecosystems Previous research from the Savin Group in the area of Environmentally Friendly Polymers was cited
