A novel method was developed with surfmer-cluster-stabilized silver nanoparticles to prepare high-performance, gradient-refractive-index (GRIN) plastic rods based on methyl methacrylate. To fabricate the GRIN plastic rods, a novel polymerizable surfactant (surfmer) of 4-(11-acryloxyundecyloxy)benzoic acid (AUBA) was synthesized. Silver nanoparticles were prepared with a reverse micelle method in the presence of the novel surfmer. During the fabrication of the silver nanoparticles, the sodium salt of AUBA was formed. GRIN plastic rods were fabricated through centrifugal polymerization and then were heat-treated at 100°G under 0.1 Torr for 24 h to remove residual monomers and water. The distribution of the surfmer-cluster-stabilized nanoparticles inside the plastic rods was studied with transmission electron microscopy (TEM). The real-image transmission through the fabricated rods was also confirmed. The results obtained in this investigation suggested that the control of the distribution of surfmer-cluster-stabilized nanoparticles could be used to fabricate GRIN rods. Furthermore, the existence of the crosslink-like surfmers increased the thermal stability of the plastic rods. The GRIN distribution of the rods was established by the dispersion of nanoparticles inside the plastic rods through TEM analysis, refractive-index analysis, and real-image transmission.
