UV 경화 수지의 연속 코팅 및 미세 패턴 성형 공정 = Continuous coating and micro pattern forming process using UV curable resin

다국어 초록 (Multilingual Abstract)

Continuous coating and forming process was studied to fabricate micro patterned film using UV curable resin. UV curable resin was dispensed and coated on the PET film passing between pattern roll and gap roll. At the same time, the micro pattern on the pattern roll was transferred on the resin layer. The coated resin layer was exposed to UV light to cure and released from the pattern roll. As the pattern becomes smaller but the height of the pattern increases, the forming process becomes more difficult especially at the stage of releasing. The relative adhesiveness of the resin to the PET film and pattern roll is very critical to this releasing process. Some parameters including surface energy of the material, degree of cure were investigated to estimate the effect on the coating and forming process.
