Abstract
This paper highlights some interesting results regarding the Single-walled carbon nanotubes (SWCNTs) functionalized by carboxylic acid, which were dispersed with ultrasonic vibration and implanted using 3-aminopropyltriethoxysilane (APTES) solution on a porous pyramidal silicon (PPS) surface. The physical characterizations of the samples were studied by both Scanning Electron Microscopy (SEM) and Atomic Force Microscopy (AFM). Also, Fourier transform infrared spectroscopy (FTIR) has been carried out. First, SEM morphological observations reveals that nano-pores dig into the sides of the micro-pyramids and SWCNTs located throughout the area Si pyramidal structure. Second, AFM confirm the information obtained by various other techniques such those of electron microscopy. Third, Fourier transform infrared spectroscopy (FTIR) analysis confirms the chemical bonding between the silicon and SWCNTs. Finally, a graphical abstract is proposed to describe the implantation steps of SWCNTs on the porous silicon (pSi) having pyramidal structure.
Schematic procedure: (step1) Formation of pyramids on silicon surface; (step2) Porousification of pyramids on silicon surface; (step3) Deposition of APTES in the surface of silicon porous structured pyramidal; (step4) Deposition of carbon nanotubes on silicon porous structured pyramidal surface with APTES.
