One-Step Plasma Synthesis of Nitrogen-Doped Carbon Nanomesh

Abstract

A one-step method for plasma synthesis of nitrogen-doped carbon nanomesh is presented. The method involves a molten polymer, which is a source of carbon, and inductively coupled nitrogen plasma, which is a source of highly reactive nitrogen species. The method enables the deposition of the nanocarbon layer at a rate of almost 0.1 µm/s. The deposited nanocarbon is in the form of randomly oriented multilayer graphene nanosheets or nanoflakes with a thickness of several nm and an area of the order of 1000 nm2. The concentration of chemically bonded nitrogen on the surface of the film increases with deposition time and saturates at approximately 15 at.%. Initially, the oxygen concentration is up to approximately 10 at.% but decreases with treatment time and finally saturates at approximately 2 at.%. Nitrogen is bonded in various configurations, including graphitic, pyridinic, and pyrrolic nitrogen.

“…Also, the elemental O content increased from 6.69 to 8.60% after the LTP treatment, and the results are shown in Table 1 2), respectively. 38 The presence of C−N bonding and the increased content of CO bonding coincide with the 3). 39,40 The results obtained from XPS demonstrate that LTP treatment is a reliable and effective approach to form new functional groups.…”

“…As for the C1s spectra of PCFs in Figure e, the peak at 284.8, 285.6, 286.3, 287.2, and 289.4 eV could be assigned to C–C, C–O, CO, C–N, and O–CO bonding, with an atomic content of 68.7, 13.5, 9.0, 7.1, and 1.7 at. % (Table ), respectively . The presence of C–N bonding and the increased content of CO bonding coincide with the observation from the full survey spectrum of PCFs in Figure c, which together demonstrate that trace N and O doping of CFs can be achieved by LTP treatment.…”

“…[11] On the other hand, the polar functional groups introduced by plasma treatment provide suitable adhesion of any subsequently deposited coating. [12] Therefore, different coatings were considered to increase and keep the stability of the hydrophilic surface for a longer period. Hydrophilic PDMS-based microfluidics can be obtained by the deposition of PVA and polyethylene glycol PEG before and after plasma treatment, at the cost of additional processing steps.…”
