Theoretical And Experimental Study The Light Scattering Nature Of PMMA Based On Mie Scattering Theory

In recent years, cross-disciplinary caused widespread concern. Soft material is a new cross-disciplinary point of condensed matter physics,chemistry,materials science and life science. Soft material is a hot topic at present. The scope of the study from single subject to multidisciplinary cross, so a large number of issues have to be solved, particularly the nature of soft material that strong response to the weak effect how to represent and how to use the nature to develop new intelligent materials with special function. However, at home and abroad , the study of the nature of strong response to the weak role is just stay in the study of the experimental phenomenon, few mathematical model had built to simulate the nature. Based on these efforts and Mie scattering theory, I had built a mathematical model to simulate the light scattering properties of the composite soft material, and then by experiment confirmed the conclusions of simulation , had obtained the following results :1. Based on the Mie scattering theory I had built a mathematical model, which may apply not only to the cases when the additions are the same type, but also can apply to the cases when the additions are various particles which have different sizes and different refractive index .2. Trace prepolymer of St have a great impact on the light scattering ability of PMMA /PS composite material. With the increase of St's content, the relationships between St' content and the light scattering ability are series of parabolas, when St's content is 0.50%, the light scattering ability of the sample is strongest.3. Trace SBR added to PS/PMMA composite material have a great impact on the light scattering properties of the sample. With the increase of MMA's content, the light scattering ability of the sample is oscillation, with the increase of SBR' content the oscillation is much more powerful; the SBR' and MMA' content is extremely trace, less than 0.1%, but make the effective light scattering ability of PS/PMMA composite material improved by 25%.4. Trace Fc or hydroxy ethyl ferrocene has a significant impact on the polymerization rate of MMA. When the quality score of Fc or hydroxy ethyl ferrocene is 0.07% and 0.10%, the polymerization rate is fastest, at room temperature can achieve rapid polymerization rate. 5. By adjusting the amount of hydroxy ethyl ferrocene, we can control the polymerization and solve the traditional problem of easy to explosive polymerization, these have a leading meaning to industrialization.
