Crosslinked polyolefin separator and manufacturing method therefor
A crosslinked polyolefin separator which has gels with a longer side length of 50 μm or more in a number ranging from 0 to 3 per 1 m2 of the separator, and shows a standard deviation of absorbance ratio between the center of the separator and the side thereof ranging from 0.01 to 0.5 is provided. A method for manufacturing the crosslinked polyolefin separator is also provided. The method includes (S1) preparing a polyolefin porous membranes, and (S2) applying a coating solution containing an initiator and alkoxy group-containing vinylsilane onto at least one surface of the porous membrane. The coating solution can permeate even to the inside of exposed pores. Thus, it is possible to provide a crosslinked polyolefin separator in which silane crosslinking occurs uniformly even inside of the pores. |

Hard coat film and method for producing same
A hard coat film having excellent adhesion (particularly adhesion over time) to a hard coat layer when a cycloolefin polymer film is used as a base material. The hard coat film comprises a hard coat layer containing an ionizing radiation curable resin laminated on at least one surface of a cycloolefin polymer base film via a primer layer. The primer layer has an arithmetic average surface roughness (Ra) in the range of 0.5 nm to 15.0 nm, and a surface of the primer layer has a static friction coefficient in the range of 0.6 to 2.0. |
