The mechanism of the surface morphology transformation for the carbon nanotube thin film irradiated via excimer laser

Abstract

In this paper, the surface morphology transformation of the sprayed carbon nanotube (CNT) thin film irradiated with the excimer laser has been systematically investigated. Under the excimer-laser irradiation, two phenomena, including the annealing and ablation effects, were found to be dependent on the incident laser energy and overlapping ratios. Moreover, the extremely high protrusions would be produced in the interface between the annealing and ablation regions. The mechanism of the CNT thin film under the excimer laser irradiation was, therefore, proposed to derive the surface morphology modifications and the further reinforced crystallinity with proper laser energy densities and overlapping ratios.

Oxygen Plasma Functionalized Multiwalled Carbon Nanotube Thin Film as A pH Sensing Membrane of Extended-Gate Field-Effect Transistor

“…A homogeneous multiwalled carbon nanotube (MWCNT) solution was obtained after an acid treatment as described in [7]. Initially, the MWCNT solution was sprayed onto the glass substrates (Eagle 2000) at 200°C to form CNTFs.…”
