| 摘 要： | 利用静电自组装技术在载波片基底上制备了壳聚糖/磺化木质素多层薄膜,并运用紫外―可见(UV-Vis)光谱等方法对其组装过程进行了表征。结果表明:壳聚糖/磺化木质素层层自组装是一个指数增长过程,其指数增长的数学模型可以描述为:Y=a×en/b+c,其中Y代表膜增长过程的吸光度、频率、质量、厚度等物理性能,n代表层数;a、b和c为常数。由于许多文献报道的自组装例也都可以用此指数增长模型进行描述,为此结合实验和文献数据对影响参数a、b和c的因素进行了探讨。 |

| Abstract: | Chitosan/lignosulfonates (CS/LGS) multilayer films were layer-by-layer self-assembled on glass substrate under electrostatic condition. Characterized by UV-Vis spectroscopy indicated that the layer growth of CS/LGS films follows the exponential growth model that could be described as: Y=a×e~(n/b)+c, where a, b and c are three parameters. Since this model was found to fit a lot of literature reported cases, the influence on this model related three parameters were discussed. |
| Keywords: | polyelectrolyte layer-by-layer self-assembly growth model parameters |
