Abstract: The following relates generally to user selection of parameters to approximate desired properties of light scattering. More specifically, in some embodiments, a graphical user interface (GUI) is provided. In some embodiments, in a forward configuration, the GUI accepts an input parameter that is a physical property or optical property of a nanoparticle material (e.g., nanoparticle size, shape, etc.), and outputs an optical effect of the nanoparticle material (e.g., a color, a graph of a reflectance fraction vs. wavelength, etc.); whereas, in an inverse configuration, the GUI accepts the optical effect as the input, and outputs a physical property or optical property of the nanoparticle material.

Abstract: The present invention provides a functional diene polymer, a preparation method thereof and a rubber composition comprising the functional diene polymer. The functional diene polymer comprises at least one type of conjugated diene structural units and silane coupler functional units represented by formula (I) in its molecular chain, and the number-average molecular weight of the functional diene polymer is 50,000˜1,000,000; R1-R4 are C1-C20 linear or branched alkyl or heteroatom-containing C1-C20 linear or branched alkyl, and the heteroatom is selected from one or more of halogen, oxygen, sulfur, silicon, and phosphorus. Not only the relationship between the wet slip resistance and the rolling resistance of the functional diene polymer is effectively improved, but also the offensive odor produced in the rubber mixing process owing to the addition of the silane coupler is reduced.
