Abstract
For antifogging materials, antifogging performance is primarily important, achieving long-lasting properties without durability loss. In the antifogging industry, hydrophilic materials are utilized to exhibit antifogging performance. However, exclusively hydrophilic materials cause a rapid reduction of durability under repeated moisture exposure. To prevent this issue, recent studies have focused on developing amphiphilic antifogging materials. In this study, to improve the properties of conventional hydrophilic antifogging material, amphiphilic ladder-like poly(phenyl-co-glycidyloxypropyl)
silsesquioxane (LPS) was synthesized via a sol-gel reaction of trimethoxyphenylsilane (PTMS) and 3-glycidyloxypropyltrimethoxysilane (GPTMS). For comparison, a hydrophilic LPS was synthesized using only GPTMS. The synthesized LPSs were coated onto glass substrates using an applicator. For each material, the chemical structure and antifogging properties were analyzed by various methods. This was supported by Korea National University of Transportation in 2026.
