Carbon Nanotube Growth Via Spray Pyrolysis, Robert Welch Call

Undergraduate Honors Capstone Projects

Spray pyrolysis is a promising method to create carbon nanotube forests (CNFs) on various surfaces. By injecting metallocene-hydrocarbon solutions into a heated quartz reactor, catalyst particles and carbon nanotubes can be formed simultaneously. Factors that affect CNF growth include the precursor concentration, injection rate and duration, carrier gas flow rate, substrate surface, growth temperature, and the composition of gases inside the reactor. The CNF morphologies affected by these factors will be presented and, hopefully, an optimum condition will be found.
