| 제목 | Organic-Inorganic Polymer Hybrids Using Polyoxazoline Initiated by Functionalized Silsesquioxane |
| 초록 | Polyhedral oligomeric silsesquioxanes (POSS), intermediate (RSiO1.5)n between silica (SiO2) and silicone (R2SiO), are an interesting inorganic particles which can replace of sol-gel derived materials. They currently have a great impact on the field of material science because of their hybrid chemical compositions with nano-sized cage structures and property enhancements via POSS to polymers. POSS is easily incorporated into common plastics by means of copolymerization or blending, requiring little or no alteration to existing synthetic processes because POSS have an inorganic SiO2 core surrounded by eight organic groups, which make it soluble in various organic solvents.1 POSS containing copolymers or blends have increased oxygen permeability, are thermoplastic or curable, have oxidation resistance, and higher thermal properties than those without the POSS moiety. Here we describe the preparation of hybrid polyoxazolines(그림 1) initiated by new POSS having only one iodopropyl group as an initiator (CubePOZO), and also of polymer hybrids from CubePOZO utilizing the sol-gel reaction of tetramethoxysilane (TMOS).2 It is expected that the introduction of the hydrophobic POSS having seven cyclopentyl groups to hydrophilic POZO can induce self-association of CubePOZO leading to the formation of hybrid micelles in an aqueous phase. We describe the properties of CubePOZO and micelle characteristics of CubePOZO in an aqueous phase. In addition, the preparation of polymer hybrids from CubePOZO and TMOS utilizing the sol-gel reaction and the effect of the hydrophobic POSS on the pore size and solvent-resistant property of the polymer hybrids are described. 참고문헌 1.
