In this study, the utilization of radiation crosslinking methods which are known as intermolecular and intramolecular crosslinking for the formation of nanoparticles of Acrylated Palm Oil (APO) in the microemulsion system that also consists of Pluronic F-127 (PF-127) surfactant was demonstrated. This microemulsion system was subjected to the ionizing radiation i.e. gamma irradiation at different doses to form the crosslinked APO nanoparticles. The effects of radiation doses on the size of APO nanoparticles were investigated using the Dynamic Light Scattering (DLS) method and their images were viewed using the Transmission Electron Microcrospy (TEM). The Fourier Transform Infra-Red (FTIR) spectroscopy was used to characterize the chemical structure and the crosslinking conversion of carbon-carbon double bond (-C = C-) of the APO nanoparticles after irradiation. As a result, the size of the APO nanoparticle decreased when the irradiation dose increased. Reduce in size might be due to the effect of intramolecular crosslinking reaction of the APO nanoparticles during irradiation process. Meanwhile, the intramolecular -C C- crosslinking conversion percentage was increased at doses below 1kGy before decreasing at the higher dose that might due to the intermolecular crosslinking of the macromolecules. This study showed that radiation crosslinking methods of polymerization and crosslinking in the microemulsion were found to be promising for the synthesis of nanoparticles.
