UV-Vis and Raman Characterization Multilayer of PMMA Films Spin Coated onto Substrate by Sol-Gel Spin-Coating Method

Article Preview

Abstract:

Different layers of PMMA spin coated onto substrate were successful prepared by sol-gel spin-coating method. PMMA was dissolved in toluene solvent and was aged for 24 hours to produce the homogeneous solution. The films were then characterized by Raman Spectroscopy and Ultraviolet-Visible (UV-Vis) spectroscopy. Raman spectroscopy studied reveals the 7 layers of PMMA film exhibit the strong and sharp intense peak at observed band around 810 cm-1 that is due to the symmetric CC4 stretching. The UV-Vis measurement present 7 layers of PMMA film have good absorption due to the small size of particles and uniform surface of the film.
