Abstract:
The present invention relates to an anti-reflection film and a manufacturing method thereof. The anti-reflection film includes an anti-reflection layer which comprises: a basic film material; and a nanocolumn pattern formed on one side of the basic material film where nanocolumns with a 1-5 ratio exsits a density of 9x10^7-1.1x10^8 piece/cm^2. The manufacturing method comprises: a step of preparing a mold with an engraved nanoporous pattern corresponding to the nanocolumn pattern; a step of coating active energy ray hardening compositions on one side of the basic material film; a step of aligning the active energy ray hardening compositions coated on the basic material film towards the nanoporous pattern on the mold; a step of advancing the basic material film while forming an anti-reflection layer composed of nanocolumns by pressurizing and touching the basic material film and the mold aligned facing each other in a rolling method using a pair of cylindrical pressurizing rollers; and a step of hardening the anti-reflection layer by radiating the active energy rays on the basic material film having passed the pressurizing roller.
Abstract:
PURPOSE: A composite porous structure including porous regions and non-porous region, a manufacturing method thereof and a separation film including the same are provided to enhance mechanical strength and stomatal density per unit area, to be utilized as a separation membrane material for a nanofiltration membrane and an ultrafiltration membrane by forming uniform sized nano pores, to selectively separate particular sized particles and to be effectively applied in bio filters for water process. CONSTITUTION: A composite porous structure (10) comprises porous regions (1) which form a nano porous structure and a non-porous region (2). The porous region is formed in a laminated form for a plurality of spherical bodies to be contacted in three dimensions. The non-porous region is formed in a structure which fills gaps between the pluralities of spherical bodies of the porous regions. The plurality of spherical bodies which forms the porous region has an interconnected structure in which adjacent spherical bodies are connected. The porous regions comprise an organic porous material, an inorganic porous material, an organic and inorganic hybrid porous material or a combination thereof.
