During the COVID-19 pandemic, the obligatory wearing of masks has led to increased consumer demand and the diversification of mask design. Accordingly, it is necessary to understand the inner meaning and characteristics of masks in the pandemic situation. Therefore, the purpose of this research is to analyze the characteristics of fashionable masks and their new cultural meaning under the COVID-19 pandemic. This research is based on literature review and empirical research. Drawing on an investigation of the historical evolution of masks and their transition under the pandemic (exhibiting differences in mask culture among countries and regions), this study analyzed 54 distinctive fashion masks designed by fashion brands and influencers that appeared from January 2020 to January 2021. The characteristics of fashion masks identified under the influence of the pandemic are as follows: Message delivery on political issues and human rights; psychological defense and expression of individuality; and conspicuous display via luxurious materials and luxury brand logos; moreover, the design of the mask uses the same material, color, pattern, decoration, and other methods as clothing to achieve the overall style. Over the course of the pandemic (and even in post-pandemic lifestyle), fashion masks are becoming more diversified conveying new social and cultural meanings.

본 연구에서는 내열성 고분자인 폴리에테르술폰을 이용하여 전기방사의 방법으로 섬유 형태의 다공성 막을 제조하였다. 여기에 Nafion 용액을 함침 시켜 고분자 전해질 연료전지용 막을 제조하였다. 열중량 분석을 통해, 현재 고분자 전해질 막으로 상용화되어 널리 쓰이고 있는 Nafion 212보다 더 높은 열적 안정성을 갖는 것을 확인하였다. 주사전자현미경 측정을 통하여, 다공성의 폴리에테르술폰 막에 Nafion 용액이 수소이온 전도체로서 잘 함침 되어 있음을 확인할 수 있었다. AC impedance 측정 결과, 100°C 이하의 온도범위에는 수소 이온 전도도가 10 -2 S/cm로 나왔으며, 100°C 이상의 범위에서는 10 -3 S/cm의 값을 나타냈다. 0.6 V, 90°C의 조건에서 389 mA/㎠의 전류밀도를 나타내었다. Nafion 212 상용 막이 75°C에서 최대 성능을 나타내는데 반해, Nafion 용액을 함침시킨 폴리에테르술폰 막은 90°C에서 최대 성능을 갖는 것으로 나타났다.
