| Abstract: | In order to improve the dispersion of TiO2 nanoparticles in PET polymer,a uniform film was uniformly coated on the surfaces of TiO2 nanoparticles by plasma polymerization of acrylic acid(AA).In this research,AA coated TiO2 nanopartiles were dispersed in ethylene glycol solution.Then AA coated TiO2/PET composite were obtained by copolymerization.DSC was used to investigate the effect of AA coated TiO2 nanoparticles on the crystal behavior of PET fuse.The results showed that AA plasma treatment process increased the crystal rate,decreased the crystal cycle and reduced the activation energies of TiO2/PET nanocomposites,as well as made the size distribution of PET crystal narrower and the crystal structure more integrated. |
