본 연구에서는 유연성을 갖는 전극 제조를 위해 환원된 그래핀 옥사이드/단일벽 탄소나노튜 브 복합체를 금이 코팅된 PET 기판 위에 스프레이 코팅하였다. 제조된 플렉시블한 전극의 전기 용량 값 은 1 M의 황산 전해질과 100 mV s-1 의 주사속도에서 82 F g-1 으로 측정 되었으며, 이 용량 값은 500 번의 굽힘 시험 후에 38 F g-1 로 감소되는 현상을 확인 하였다. 또한, 이러한 결과는 정전류 충 방전과 전기화학 임피던스법을 포함한 전기화학적 분석 결과와도 부합하는 결과를 나타내었다. 유연성을 갖는 환원된 그래핀 옥사이드/단일벽 탄소나노튜브 복합체 전극은 500회의 반복적인 굽힘 시험 후에도 대략 50%의 초기 전기 용량 값을 유지 할 수 있었으며, 이러한 여러 가지 전기화학적 특성을 고려하여 볼 때 미래 개발 가능한 플렉시블한 에너지 저장 매체로써의 적용이 가능 하다는 점을 확인 할 수 있었 다.

Purpose – Blockchain technology, which has the characteristics of credibility, security, integrity and decentralization, has brought innovation to internet platforms that mediate peer to peer transactions, as well as changes to the contents distribution services. Blockchain-based copyright distribution platforms can solve problems which have been articulated on prior internet social networks: increased market dominance of platform business because of centralization with no reward to creators who upload on platforms, and lack of fairness, such as unfair profit distribution between the copyright holder and businesses. With this background, the current research confirmed the factors that affect the intention of usage and behaviors, targeting potential users of blockchain-based copyright distribution platforms. Research design, data, and methodology – Centered around the UTAUT2 Model, the research model was designed with 'Perceived Security' added as Construct, and 'Age' and 'Knowledge Level' added as moderating variables. For data, 607 responses were collected by an online survey, and 601 responses were included in the final analysis. We analyzed the research model and sample by using SPSS 23.0 and AMOS 23.0 on the collected responses. Results – First, results of research on whether Constructs make positive effects on Intention of use is: social influence, facilitating conditions, habit, and perceived security had positive effects on intention of use, and performance expectancy, effort expectancy, hedonic motivation, and economic value did not. Second, results of the research on whether facilitating condition, habit, and intention of use made an impact on using behaviors, it was shown that only habit and intention of use made positive effects. Third, in two groups divided by age above or under 40, group effort expectancy, intention of use, habit, and intention of use had controlling effects, and facilitating condition, intention of use, perceived security, and intention of use had effects in both groups. Conclusions – The research shows that no matter how great a blockchain-based platform is, if advantages of blockchain are not proved in various industries and utilized in real life like the internet, blockchain-based distribution systems will develop slowly. Rather than a short-term inducement emphasizing technology, there is a need for a strategic approach that can foster the environment.
