Metal mold, process for manufacturing the same, and molded article produced using the mold

摘要

The mold has a mold surface on which is formed as a release film a water-repellent and oil-repellent fluorocarbon-based chemisorbed film having a thickness that is uniform in nanoscale and having a controlled surface energy. As a result, even when a mold has an ultrafine shape on the nanometer scale, the mold allows high precision molding excellent in fluidity and penetrativity of a molding material. In addition, this mold eliminates the application of a release agent and can prevent a release agent from adhering to a molded article.

主权项

1. A method for manufacturing a releasable mold, comprising:
bringing a mold surface into contact with a composite film-forming solution to allow them to react with each other to form a releasable composite film, the solution being obtained by diluting, with an organic solvent: a long-chain substance (1) having one of Formula 3, Formula 4 or Formula 5 a short-chain substance (2) having a formula CF3—(CF2)o—(CH2)2—Si(OA)3, wherein subscript o represents an integer, A represents an alkyl group, and OA represents one of a Cl or NCO, the long-chain substance exhibiting a molecule length that is greater than a molecule length of the short-chain substance; a third substance (3) having a formula (AO)3Si(OSi(OA)2)pOA, wherein p represents 0 or an integer, A represents an alkyl group, and OA represents one of a Cl or NCO; and a silanol condensation catalyst, an other catalyst or a combination thereof.
