Problems solved by technology

However, when light in the visible region is used, it is difficult to generate active oxygen to such an extent that sufficient antibacterial activity can be exhibited, and the produced active oxygen exists only for a very short time
Therefore, there is a limitation that excess light energy must be irradiated for a relatively long time

preparation Embodiment 1

[0080] 5 g of AOI-VM (M.W.141.25) from Karenz and 40 g of AOI-VM from Bayer as polyester-carbonate diol C1200 (equivalent: 1000) was dispersed in 20 g of acetonitrile solution, a small amount of DBTDL as a catalyst was added thereto, and then reacted at room temperature for 5 hours to prepare a urethane acrylate oligomer (polymer).

[0081] Then, if figure 1 As shown in , it was confirmed by infrared spectroscopy whether urethane acrylate was produced (at 1630cm -1 nearby enhanced peaks).

preparation Embodiment 2

[0083] 5 g of AOI-VM (M.W.141.25) from Karenz and 40 g of AOI-VM from Bayer as urethane-carbonate diol C850 (equivalent: 1000) was dispersed in 20 g of acetonitrile solution, a small amount of DBTDL as a catalyst was added thereto, and then reacted at room temperature for 5 hours to prepare a urethane acrylate oligomer (polymer).

preparation Embodiment 3

[0085]5 g of AOI-VM (M.W.141.25) from Karenz and 40 g of Desmophore VPLS 2249 / 1 (equivalent weight: 100) from Bayer as polyester-carbonate diol were dispersed in 20 g of acetonitrile solution, to which a small amount was added DBTDL as a catalyst, and then reacted at room temperature for 5 hours to prepare urethane acrylate oligomers (polymers).

Abstract

The present invention relates to an antimicrobial polymer coating composition comprising a urethane acrylate-based oligomer or polymer with a molar ratio of urethane functional groups to (meth)acrylate-based functional groups of 1 to 10; a photosensitizer; and a photoinitiator, and to an antimicrobial polymer film comprising a cured product of the antimicrobial polymer coating composition; a predetermined urethane acrylate-based polymer resin; and a photosensitizer dispersed in the polymer resin, wherein the antimicrobial polymer film has an oxygen permeability of 5 to 100 cc / m2 day.

Description

technical field [0001] Cross References to Related Applications [0002] This application claims the benefit of the filing date of Korean Patent Application No. 10-2017-0131520 filed at the Korean Intellectual Property Office on October 11, 2017, the entire contents of which are incorporated herein by reference. [0003] The invention relates to an antibacterial polymer coating composition and an antibacterial polymer film. Background technique [0004] Photosensitizers absorb light to generate reactive oxygen species (ROS), and photodynamic therapy (PDT) is widely used, in which photosensitizers are excited to generate reactive oxygen species or free radicals when irradiated with light of a specific wavelength from the outside, thereby inducing Apoptosis of various lesions or cancer cells and destroys them. [0005] Various attempts have been made to develop polymeric materials with antimicrobial activity using this photodynamic reaction. For example, Korean Patent No. ...
