| 英文摘要 | Filming process of polystyrene nano-latex (NPS) particles was studied by a combination of various methods. For a constant annealing time of 1 h, the AFM images showed that the deformation and sintering temperatures for NPS particles were ca. 90 degreesC and 100 degreesC respectively. In spin-lattice relaxation measurements of solid state NMR, it is found that T-1L, T-1S and I-1L/I-0 increased significantly after annealing at 90 degreesC and above. DSC results showed that there was an exothermic peak near T-g after annealing for 1 h at the selected temperatures below 95 degreesC; otherwise, the exothermic peak disappeared after annealing at 100 degreesC or above. The apparent density of NPS increased suddenly in the temperature range. The results implied that the macromolecules in NPS particles are in a confined state with higher conformational energy and less cohensional interactions which are the drive force for the sintering at a lower temperature compared with the multichain PS particles and the bulk polymer. |
