MULTIFUNCTIONAL NANOTUBES
The objective is to demonstrate that physical properties of multifunctional material systems can be tailored for specific applications by controlling different types of nanotubes, their concentration and degree of alignment. The properties of structured polymers can be enhanced by combining nano tubes with desired properties to form a nano polymer. These may have the potential to provide structural integrity as well as sensing and/or actuation capabilities. By proper selection of the polymer matrix to promote donor acception and/or dispersion interactions can improve adhesion at the interface between the nano- tubes and hence also the polymer matrix significantly. An effective sensor material that responds to strain, stress, pressure, and temperature can be yielded by using very small loadings of single wall nanotubes in a polyimide matrix. These materials also exhibit significant actuation in response to applied electric fields. Alternative thermodynamic routes involve enhancing polymer/SWCNT interactions via amphiphilic surfactants, hydrophobic interaction with nanotubes, physical wrapping with conjugated polymers which exhibit enhanced dispersion interactions by adopting a n-stacked geometry , donor-acceptor interactions via charge transfer , Zwitterion complex formation , and nonspecific interactions using DNA or peptide sequence.
