Figure 3From: Preparation and ageing-resistant properties of polyester composites modified with functional nanoscale additivesParticle size distribution of the nano-TiO 2 samples. (a) Without modification and (b) modified with aluminate coupling agent; FE-SEM images of the polyester/nano-TiO2 composites: (c) the nano-TiO2 was not modified, and (d) the nano-TiO2 was modified with aluminate coupling agent.Back to article page
