Abstract

In this study, the effect of nanoparticles on the interaction between cellulose chains in solution state was investigated. Halloysite nanotube (HNT) and HNT modified with sodium dodecanoate (NaL) were added to cellulose solutions, respectively, and the rheological behaviors of each solution were investigated. The pristine HNT interrupted the inter- and intra-molecular hydrogen bonding between cellulose chains and the solutions showed different phase transitions and rheological behaviors compared to homo-cellulose solution. However, the NaL modified HNT merely affected the hydrogen bonding between cellulose chains and showed similar physical state with homo-cellulose solution. This study is expected to be helpful for the research on functionalization of cellulose products by introducing anisotropic fillers.


본 연구에서는 나노입자가 용액 내에서 미세결정질 셀룰로오스(MCC) 사슬의 거동과 상호작용에 미치는 영향을 관찰하였다. 이를 위하여 sodium dodecanoate(NaL)로 개질된 halloysite nanotube(HNT)와 개질되지 않은 HNT를 각각 MCC 용액에 첨가하여 유변거동을 고찰하였다. 개질되지 않은 HNT는 MCC 사슬 간·사슬 내 수소결합을 방해하여 순수 MCC 용액과 다른 상전이 및 유변거동을 보였으나, NaL로 개질된 HNT의 경우 MCC의 수소결합에 미치는 영향이 적어 순수 MCC 용액과 유사한 물리적 상태를 보여주었다. 본 연구결과는 이방성 나노입자 도입에 따른 MCC의 기능성 조절 연구에 기초자료로 활용될 수 있을 것으로 기대된다.
