#기체차단성
나노셀룰로오스는 높은 결정성과 강한 수소결합으로 인해 기체 차단성을 보유하고 있습니다. 나노셀룰로오스의 결정성 영역은 기체 분자가 통과할 수 없는 불투과성 영역이며, 결정성과 수소결합의 영향으로 기체가 필름을 통과하기 어려운 복잡한 경로 (tortuous path)가 만들어져 기체 차단성이 향상됩니다.
# 고강도 / 경량성
셀룰로오스는 결정 형태에서 약 100-200 GPa의 이론 탄성계수와 약 4.9-7.5 GPa의 인장강도를 갖는 높은 기계적 특성을 가지고 있습니다. 이러한 기계적 특성은 대부분의 금속, 세라믹, 합금, 합성 폴리머보다 높은 수준이며 1.6 g cm-3 정도의 낮은 밀도로 인해 경량성도 우수한 소재입니다.
# 유변학적 특성
나노셀룰로오스는 외력에 의한 점성도 변화인 요변성으로 인해 외부의 힘이 작용할 때는 점성이 감소하여 졸로 변화하였다가 외부 힘의 작용이 없을 때에는 점성이 증가하여 다시 겔 형태로 돌아오는 현상을 나타냅니다.
