  • Publication number: 20210100753
    Abstract: There is provided a method of preparing silica nanocapsules, the method comprising mixing a surfactant with water at a temperature that is above the gel-to-liquid transition temperature of the surfactant to form a mixture, passing the mixture one or more times through at least one pore to obtain a dispersion of vesicles, and adding a silica precursor to the dispersion of vesicles to form silica nanocapsules. Also provided is a silica nanocapsule formed from a vesicle template, and a method of delivering one or more types of molecules to a subject. In a specific embodiment, hollow silica nanocapsules having substantially lens-shaped are synthesized by employing dimethyldioctadecylammonium bromide (DODAB) or dioctadecyldimethyl ammonium chloride (DODAC) as the vesicle template and tetraethyl orthosilicate (TEOS) as the silica precursor.

  • Patent number: 10941249
    Abstract: The present invention relates to a method of preparing a polyphenylene sulfide and a high-viscosity polyphenylene sulfide prepared using the method. In this method, the ratio of an organic phase to an aqueous phase is controlled by controlling dehydration conditions, so that high viscosity may be realized without adversely affecting a reaction or physical properties during preparation of the polyphenylene sulfide.
