Direct amination of boron-doped diamond by plasma polymerized allylamine film

Abstrakt

A novel microwave pulsed-plasma based method for the modification of the hydrogen-terminated polycrystalline boron-doped diamond (BDD) with a thin film of polymerized allylamine (PPAAm) is reported. A modified BDD surface is resistant to hydrolysis and delamination and is characterized by a high density of positively charged amino groups. Pulsed microwave plasma was applied to improve the degree of cross-linking and bonding of the plasma polymeric films to BDD. The primary amino groups of the amine-modified Si/BDD surface were coupled with antraquinone derivatives as model electroactive compounds. Synthesized thin BDD-PPAAm films were investigated with X-ray photoelectron spectroscopy (XPS), laser induced fluorescence (LIF) and Fourier transform infrared spectroscopy (FT-IR). The FT-IR studies confirm that the molecular structure of the deposited layer reproduces the monomer structure with a partial transformation of amino groups into amide and nitrile. XPS results show that PPAAm film on an Si/BDD electrode is electrochemically stable within the range of polarization potentials between −1.1 and +1.1 V. The fluorescence properties of the PPAAm modified BDD surface makes its promising for application in sensors with optical readout. At the same time, the PPAAm film's durability investigated over a wide potential range makes it ideal for electrochemical sensors
