If they could be easily exfoliated, layered materials would become a diverse source of two-dimensional
crystals whose properties would be useful in applications ranging from electronics to energy
storage. We show that layered compounds such as MoS2,WS2, MoSe2, MoTe2, TaSe2, NbSe2, NiTe2,
BN, and Bi2Te3 can be efficiently dispersed in common solvents and can be deposited as individual
flakes or formed into films. Electron microscopy strongly suggests that the material is exfoliated
into individual layers. By blending this material with suspensions of other nanomaterials or
polymer solutions, we can prepare hybrid dispersions or composites, which can be cast into films.
We show that WS2 and MoS2 effectively reinforce polymers, whereas WS2/carbon nanotube
hybrid films have high conductivity, leading to promising thermoelectric properties.
Graphene으로부터 촉발된, 2D nanomaterials에 대한 관심이 layered TMDs로까지 이어진 연구입니다.
이 논문때문인지는 모르겠으나, 때를 같이하여 주저자이자 교신저자인 Prof. Jonathan N. Coleman 교수님은 어제 TV 뉴스에 출연하셨다고 하는군요.
6개 그룹의 협력연구인지라 다소 부담스러울 정도로 긴 저자목록을 갖게되었지만, 이것이 궁극적으로 나아가야할 방향의 하나라고도 생각됩니다.
교수님의 배려로 좋은 기회를 마련해주셔서 이러한 유명논문지에 이름을 올릴 수 있게되어 굉장히 기쁩니다만,
지면상의 이유로 두 senoir 그룹을 제외하고는 논문사사를 하지 못한게 무척이나 안타깝네요.
준비하면서 깨닫게 된 부족한 점들은 이어질 연구에 뼈가 되고 살이 되리라 믿습니다.
마지막으로 교수님과 (연구실에서의 부재를 이해해주고 있는)연구실원들에게 재차 고마움을 전합니다. |
