AFM-IR spectra confirms distribution of hybrid inorganic/polymer phases on photoluminescent PET fibers

(December 18, 2014 Santa Barbara, CA) – A new publication from a textile engineering team, led by Professor Jesse Jur at North Carolina State University, highlights the use of vibrational spectroscopy to study reaction mechanisms between trimethylaluminum (TMA) vapor and polyethylene phthalate (PET) fibers. These materials are candidates for new classes of flexible electronic devices and sensors. The work shows clear evidence of formation of a hybrid phase within the polymer matrix, and differences in the extent and reaction mechanism depending on processing conditions. The Anasys Instruments nanoIR was used to map the extent of reaction on treated cross sections, producing diagnostic spectra at the fiber-vapor interface and into the bulk fiber with submicron spatial resolution. Check this Journal of Materials Research page to reference the full report.
