Abstract : Perpustakaan Tuanku Bainun
This study aims to characterise 4-Sulfocalix[4]arene (SC[4]) thin films using Atomic Force Microscopy (AFM) in analysing its thickness and surface morphology. Quartz substrates were cleaned using ultrasonic cleaning with an Elmasonic P70H. SC[4] thin films were then fabricated on a quartz surface using WS-400BZ-6NPP/A1/AR1 model spin coater from Laurel Technologies, producing thin films with 5, 10, 15, and 20 layers. Each thin film was characterised in the tapping mode of the AFM Park System NX-10. Scans were conducted on different film areas of different scales, and the data were analysed using XEI Data Processing and Analysis Software. Height measurements obtained via Line Profile analysis revealed a progressive increase in film thickness with the additional layers, demonstrating a significant linear relationship. AFM images showed precise 2D and 3D surface topography, indicating that the thin films became uneven and non-uniform with the addition of more layers. The findings demonstrated a linear relationship between film thickness and the number of layers, measuring 58.175 nm for 5 layers, 77.626 nm for 10 layers, 84.608 nm for 15 layers, and 94.806 nm for 20 layers. The surface roughness of thin films was also determined, and it is significantly influenced by the number of layers, as illustrated by the root mean square roughness (Rq). The values were found to be 26.512 for 5 layers, 29.777 for 10 layers, 30.177 for 15 layers, and 31.093 for 20 layers, respectively. This increase in surface irregularity indicates that the deposition process leads to progressively irregular surfaces with an additional number of layers, as proven by equivalent studies on thin films. This study emphasised the effectiveness of AFM in thin film research by demonstrating its precision in measuring thickness and analysing surface topography.
