Preparation and optical characterization of latex nanoparticles / Mohd Hafiz Hassan.

Latex is a stable dispersion of polymeric material in an essentially natural or synthetic colloidal suspension. Latex nanoparticle is latex in nano (10-9m) size and used for coating or emitter. In this research, three types of latex nanoparticles samples with different amounts of n-BMA were prepared. The parameter used are drying process which is blow process, fast drying process and slow drying process. The chemical components of the latex nanoparticles were investigated by Fourier transform infrared (FTIR) spectrometer and the FTIR spectra exhibited the characteristic stretching peaks of C-H (CH2) at 2928 cm-1 , the stretching vibration of C=0 was observed at 1739 cm-1 , and the absorption at 970 cm-1 was the characteristic peak of n-BMA. UV-Vis absorption spectra show peaks characteristic of the surface of latex nanoparticles and the film absorption to UV light reached its maximum at range 256- 273 nm.
