Welcome to NanoCPI online, the virtual home of the Rina Tannenbaum lab at Georgia Tech!
By studying organic-inorganic interfaces, we investigate the chemical and physical properties of intricate composites. For example, below are some of our current projects.
Our group has successfully aligned and oriented carbon nanotubes in a polymeric matrix. Alignment and orientation are critical steps toward practical carbon nanotube-based composites.
Electroactive Organometallic Polymers
The efficient synthesis of stable electrically conductive metal-organic polymers is a formidible and significant task in engineering. Our current efforts include predicting crystal structures, hastening synthesis, and improving stability to ambient air.
Cellulosic Nanocomposites A
Biopolymer as Filler
Cellulose nanofibers, also known as cellulose whiskers, serve as effective, inexpensive, and eco-friendly additives to polymeric media for improvement of mechanical properties. Our lab focuses on reactive molding of polymeric nanocomposites reinforced with these whiskers in order to achieve a fine and uniform particle distribution.
Cellulosic Nanocomposites B
Biopolymer as matrix
Cellulose can be used not only as a filler in composites but also as the matrix phase. We focus on in-situ synthesis of nanoparticles within cellulosic media, which results in extremely stable suspensions of iron and iron oxide nanoparticles.
The degree of success of artificial bone implants--such as those made out of titanium--depends upon the physical and chemical characteristics of the implant's surface. Our lab quantitatively characterizes implant surfaces in order to make empirical, statistically supported, statements about the effects of surface properties, such as roughness, topography, and surface energy, on the osseointegration process.
