The synthesis homogenous of poly(methyl methacrylate) by varying the amount of<br />

monomer and surfactant via surfactant polymerization was carried out to obtain<br />

nanoparticles of polymer range from 100nm to 200nm which is potential to act as a<br />

substrate in organic light-emitting diode (OLED). Surfactant polymerization was used<br />

to evaluate the fabrication of photonic crystal of thin film. Characterization of the<br />

synthesized polymer were carried out by using Fourier Transform Infrared<br />

spectroscopy (FTIR), Scanning electron microscopy (SEM), Thermogravimetric<br />

analysis (TGA) and Ultraviolet-visible spectroscopy (UV-Vis). IR spectrum shows an<br />

absorption bands namely, ν(O–CH3), ν(C=O), ν(C–H) and ν(C–O) which can be<br />

observed at range 2952cm -1 , 1727cm -1 , 1450cm -1 and 1149cm -1 . For thermograms,<br />

the final stage of degradation of polymer is the ranging 330°C to 450°C. Besides, from<br />

UV-Vis analysis there is peak absorption at 300nm to 400nm. Meanwhile, for SEM<br />

analysis shows the PMMA has homogenous sizes and closely-packed arrangement.<br />
