Disclosed are injection moldings, an injection-molding apparatus and a method thereof. The injection-molding apparatus comprises: a cavity mold having a cavity; a core mold having a core surface to form a molding space for injection moldings when being joined to the cavity mold; a heating unit for heating the cavity mold or the core mold; a cooling unit for cooling the cavity mold or the core mold; and a patterning stamp having a micrometer or nanometer sized pattern and provided on an inner surface of the molding space. According to the injection-molding apparatus, a micrometer or nanometer sized pattern is formed on a surface of injection moldings so as to have a super-hydrophobic characteristic and an optical characteristic, and a micrometer or nanometer sized pattern of a complex structure can be implemented.

Injection moldings, injection-molding apparatus and method thereof

An ultra-hydrophilic Ti&#x2014;O&#x2014;C based nano-film of which deposition thickness was improved and deposition uniformity was excellent was fabricated by mixing a Ti precursor and a liquid having a low boiling point and a high volatility&#x2014;at a uniform ratio. The catalyst accelerates a vaporization of the Ti precursor and facilitates the Ti precursor to be injected into a reaction chamber, thereby improving plasma polymerization efficiency.
