Abstract
Description
図1に示すように、本発明に係る第1の実施形態において、ポリエステル材料1と、ポリエステル材料1に均一に分散する抗菌複合体2とを含む、透明抗菌フィルムZを提供する。
図2に示すように、本発明は、ナノ粉体及び抗菌前駆体を焼結することにより、前記抗菌複合体を得ること(ステップS1)と、ポリエステル材料と抗菌複合体とを混合することにより、抗菌マスターバッチを製造すること(ステップS2)と、前記抗菌マスターバッチを用いて透明抗菌フィルムを形成すること(ステップS3)と、を少なくとも含む、透明抗菌フィルムの製造方法を提供する。
本発明に係る透明抗菌フィルムが、抗菌効果を有することを証明するために、上述した透明抗菌フィルムの製造方法に基づいて実施例1~3に係る透明抗菌フィルムを製造し、また、比較例1として抗菌剤を含まない透明フィルムを製造したと共に、比較例2として抗菌剤を含むものの抗菌複合体の屈折率が1.66より高い透明抗菌フィルムを製造した。実施例1~3及び比較例2の透明抗菌フィルムの成分は、表1に示す通りである。
図3に示すように、本発明に係る透明抗菌フィルムZは、基材9の両面にそれぞれ透明抗菌フィルムZが設置されるように、基材9に積層されることにより、透明抗菌基材Yが形成されることができる。それによって、基材9にも抗菌及び防カビ効果を与える。透明抗菌フィルムZは、上述と類似するポリエステル1及び抗菌複合体2を含むので、ここでその説明を省略する。
本発明の有利な効果として、本発明に係る透明抗菌フィルム及びその製造方法は、「前記抗菌複合体は、前記ポリエステル材料に分散する」及び「前記抗菌複合体の屈折率が1.46~1.66である」といった技術特徴により、透明抗菌フィルムは、抗菌効果及び本来の光学特性を両立することができる。
