Abstract: A graft copolymer, a thermoplastic resin composition including the graft copolymer, and a method of preparing the thermoplastic resin composition are described herein. A graft copolymer having a shell in which silica modified with a specific compound is dispersed within a specific content range, a thermoplastic resin composition including the graft copolymer, and a method of preparing the thermoplastic resin composition are also described herein. Since silica modified with a specific compound is dispersed in the periphery of rubber particles, that is, in the shell of the graft copolymer, the dispersibility of the graft copolymer may be improved. Therefore, the graft copolymer may have transparency equal to or better than a conventional graft copolymer. In addition, compared to a resin composition having an equivalent rubber content, the thermoplastic resin composition described herein may have excellent physical properties, such as impact strength and tensile strength.

Abstract: Functional nanocomposites containing nanoparticles of different chemical compositions may exhibit new properties to meet demands for advanced technology. It is imperative to simultaneously achieve hierarchical structural control and to develop rapid, scalable fabrication to minimize degradation of nanoparticle properties and for compatibility with nanomanufacturing. The assembly kinetics of supramolecular nanocomposite in thin films is governed by the energetic cost arising from defects, the chain mobility, and the activation energy for inter-domain diffusion. By optimizing only one parameter, the solvent fraction in the film, the assembly kinetics can be precisely tailored to produce hierarchically structured thin films of supramolecular nanocomposites in approximately one minute. Moreover, the strong wavelength dependent optical anisotropy in the nanocomposite highlights their potential applications for light manipulation and information transmission.

Abstract: A process for preparing a phase change microcapsule having a thermally conductive shell is introduced. The thermal conductivity of the encapsulation materials for the phase change microcapsules is increased by adding thermally conductive nano-materials.

Thereafter, the phase change microcapsule having the phase change material as the core and the thermally conductive material-containing copolymer as the shell is prepared. The polar functional groups on the surface of the thermally conductive inorganic material condense with the vinylsilane compound to form chemical bonding, thereby substantially increasing the compatibility between the thermally conductive inorganic material and the copolymer.
