Synthesis and characterization of hyperbranched poly(urea-urethane)s
The thesis aims to synthesize hyperbranched poly(urea-urethane) polymers (HPU) in one-pot method using commercially available monomers which are 2,4-toluylene diisocyanate (TDI) as aromatic diisocyanate and isophorone diisocyanate (IPDI) and 2(3-isocyanatopropyl) cyclohexylisocyanate (IPCI) as …

Behavior of reinforced concrete column-beam joint subjected to close in blast loads with polyurea and FRP sheets
… performance of various coatings like Poly urea and FRP Sheets. Numerical models were first validated against experimental contact-explosion tests on RC bridge columns (Yuan et al., 2017) achieving close agreement in peak accelerations and damage profiles. Complementary boundary …

Non-covalent Intermolecular Interactions in Polymer Design: Segmented Copolymers to Non-viral Gene Delivery Vectors
… properties of a given system, from segmented copolymers to interactions of functionalized polymers with non-viral nucleic acids delivery vehicles. The ability to control the intermolecular interactions of a given system allow for tailoring of that system to yield a desired outcome, whether it is …

Autonomic healing of low-velocity impact damage in woven fiber-reinforced composites
Polymer-matrix fiber-reinforced composites have seen increasing use in applications requiring high specific strength and stiffness. These materials typically show excellent in-plane properties but are particularly susceptible to transverse impacts. Impact can significantly reduce strength and the …
