Abstract: The present invention discloses polymer surfaces with T-shaped microstructure and their fabrication method and applications. The polymer surfaces with the T-shaped microstructure are characterized in that T-shaped microposts arrange orderly on them, and nanobulges arrange orderly on the top surfaces of the micronails of the T-shaped microposts. A flexible insert is designed and manufactured according to the geometry of the T-shaped microposts, and nanogrooves are manufactured on the cavity surface of an injection mold according to the geometry of the nanobulges on the top surfaces of the micronails. The flexible insert is mounted on the injection mold cavity. An injection molding machine is used to inject the molten polymer into the injection mold cavity. Then the polymer surfaces with the T-shaped microposts, on the top surfaces of the micronails of which the nanobulges arrange orderly, are molded. The polymer surfaces with the T-shaped microstructure exhibit robust Cassie-Baxter state and moderate surface adhesion to water droplets, and can be used for quantitative collection, lossless transportation or micromixing of microdroplets.

Abstract: The present invention relates to micro-/nanostructured compound-eye arrays and fabrication method thereof, and discloses a fabrication method and applications for the molded polymer parts with the micro-/nanostructured compound-eye arrays on their surfaces, which exhibit both hydrophobicity and light trapping. The fabrication method for the molded polymer parts with the micro-/nanostructured compound-eye arrays includes following steps. A flexible microlens array template is assembled; the flexible microlens array template is fixed on an injection mold cavity, and a polymer part with microlens arrays distributing on its surface is molded by using injection molding; the microlens arrays on the molded polymer part are imprinted onto the surface of an ultra-pure aluminum foil, nanopores are formed on its surface via anode oxidation, and so an aluminum template with negative micro-/nanostructured compound-eye arrays is fabricated; the aluminum template is fixed on an injection mold cavity, and a polymer part with micro-/nanostructured compound-eye arrays distributing on its surface is molded by using injection molding. The dual-level compound-eye arrays (orderly distributed convex semi-sphere microlens and densely distributed nanopillars) are developed on the surface of the molded polymer part, which exhibits both hydrophobicity and light trapping.

Abstract: An extrusion blow molding machine comprises an extrusion apparatus, an electrically-driven parison thickness programming apparatus, an electrically-driven mold-clamping apparatus with a dual-driving function, and a frame, wherein the extrusion apparatus, the parison thickness programming apparatus and the mold-clamping apparatus with a dual-driving function are installed on the frame. The mold-clamping apparatus with a dual-driving function comprises a driving assembly, a mold-opening/closing assembly, a mold-moving assembly, and a base. The driving assembly includes a servo motor, which actuates both mold-opening/closing and mold-moving assemblies, respectively. The parison thickness programming apparatus is driven by asynchronous motors, which run in a single direction continuously to result in a required axial parison thickness distribution. An extrusion blow molding method is realized using the machine. The present extrusion blow molding machine has an obviously simplified and compact structure, thereby reducing the manufacturing cost, lowering the energy consumption, and improving the transmission efficiency and position accuracy.
