M. Salih, Ashraf and Wan Yunus, Wan Md Zin and Mohd Dahlan, Khairul Zaman and Mahmood, Mohd Hilmi and Ahmad, Mansor (2012) UV-curable palm oil based-urethane acrylate/clay nanocomposites. Pertanika Journal of Science & Technology, 20 (2). pp. 435-444. ISSN 0128-7680; ESSN: 2231-8526

Abstract / Synopsis

Synthesis of palm oil based-urethane acrylate (POBUA) resins was carried out by acrylation of epoxidized palm oil (EPOP) using acrylic acid in the presence of a catalyst and followed by isocyanation to obtain the POBUA. Using the monomer as a diluent in the formulation, 4% of photoinitiator and incorporation of organoclay (1-5% wt), nanocomposites were obtained upon UV irradiation. The X-ray Diffractory XRD study revealed that the nanocomposites obtained were of the exfoliation type. The presence of the clay improved the hardness and did not affect the thermal stability. Similarly, it increased the glass transition temperature Tg but reduced the modulus as the clay content was increased. The improvement of the tensile strength was only obtained when the clay concentration was 5 phr.
