In this review, we focus on one of the most attractive biomaterials, microfibrillated cellulose (MFC). MFC, a type of nanocellulose, mainly originates from cellulose in lignocellulosic biomass. MFC represents one of incredible important natural resources due to its abundancy, renewability, and susta...

마이크로피브릴화 셀룰로오스가 아직 상업적으로 많은 주목을 받지 못하는 이유는 무엇인가? | 이로 인해 마이크로피브릴화 셀룰로오스는 높은 표면적과, 높은 aspect ratio, 그리고 특이적인 용해성을 가지게 되고, 이는 전통적인 목재 산업 뿐만 아니라, 최신식의 식품/바이오/화학/의료 산업에 이르는 다양한 영역에의 적용 가능성을 보여주는 주요한 원인이 된다. 한편 이러한 응용력에도 불구하고, 아직 마이크로피브릴화 셀룰로오스는 제조 시 필요한 높은 에너지량과 반응성 조절의 어려움 때문에 상업적으로 많은 주목을 받지 못하고 있다. 따라서, 마이크로피브릴화 셀룰로오스의 기질에 대한 특성을 이해 및 구체화하고, 마이크로피브릴화 셀룰로오스의 피브릴화도를 선택하며, 표면의 개량을 선택적으로 조절할 수 있는 시스템을 개발하는 연구가 필요할 것이다. | |
바이오매스의 활용에 대한 필요성이 높아지는 이유는 무엇인가? | 최근, 석유에너지 고갈에 따른 바이오리파이너리(biorefinery) 의 필요성 확대, 에너지 독립에 대한 끊임없는 요구, 이산화탄소 배출권 확보 등 기후 변화에 대한 대응의 일환, 그리고 우리 사회에 지속성장가능성을 제공한다는 측면에서 바이오매스(biomass)의 활용에 대한 필요성은 날로 높아지고 있다 [1]. 그 중에서도 옥수수 등을 포함하는 1세대 바이오매스의 연구는 식량자원이라는 한계점을 지니고, 따라서, 2세대 리그노셀룰로오스계 바이오매스(lignocellulosic biomass)가 바이오에너지 및 바이오 화학소재 개발에 필요한 주요 대체 자원으로 일조하고 있다[2]. | |
마이크로피브릴화 셀룰로오스는 주로 어떻게 생성되는가? | 마이크로피브릴화 셀룰로오스는 리그노셀룰로오스계 바이오매스의 셀룰로오스에서 유래한 섬유로 풍부하고, 재생가능하며, 지속 가능한 천연 소재의 일종이다. 주로 물리적 전처리에 의해 생성되며, 나노미터에서 마이크로미터에 이르는 다양한 소섬유들의 결합으로 이루어져 있다. 이로 인해 마이크로피브릴화 셀룰로오스는 높은 표면적과, 높은 aspect ratio, 그리고 특이적인 용해성을 가지게 되고, 이는 전통적인 목재 산업 뿐만 아니라, 최신식의 식품/바이오/화학/의료 산업에 이르는 다양한 영역에의 적용 가능성을 보여주는 주요한 원인이 된다. |
