Description
まず、ベース層、ハードコート層、及び銀ナノワイヤ層が順次積層された積層構造体を準備し、銀ナノワイヤの量が異なるために表面抵抗が<10、15、20、150 opsである銀ナノワイヤ層を実施例1~実施例4としてそれぞれ準備する。ベース層、ハードコート層、高屈折層、低屈折層が順次積層された積層構造体を比較例1として準備する。本評価では、実施例1~実施例4及び比較例1の積層構造の透明度、ヘイズ及び反射率を試験する。また、実施例1~4及び比較例1のベース層の第2の表面を50℃(T1)に設定した恒温加熱板に取り付けて、断熱効果の評価方法を実施する。熱平衡後、実施例1~実施例4の銀ナノワイヤ層及び比較例1の低屈折層の露出面の温度(T2)を熱撮像装置(赤外線(IR)カメラ)で測定する。断熱効果は、2つの面の温度差(△T)から評価する。評価結果を表1に示す。銀ナノワイヤ層の表面抵抗が10 ops未満である場合、銀ナノワイヤ層中の銀ナノワイヤの量は、透明断熱フィルムの視認性に影響を及ぼし得ることに留意されたい。反対に、銀ナノワイヤ層の表面抵抗が150 ops超の場合、断熱効果は非効率的である。
