Microfibrillated cellulose (MFC): pullulan bionanocomposite films

Green Process for Impregnation of Silver Nanoparticles into Microcrystalline Cellulose and Their Antimicrobial Bionanocomposite Films

A novel greener method to impregnate silver nanoparticles (AgNPs) into microcrystalline cellulose (MCC) by curry leaf (Murraya koenigii) extract is presented. The active reduction of silver ions by curry leaf extract was explored for the in situ impregnation AgNPs into MCC. Transmission electron microscopy (TEM) analysis of MCC coated with AgNPs showed the formation of silver particle sizes in ...

Functional Polymer Nanocomposite Materials from Microfibrillated Cellulose

Biomimetic Aerogels from Microfibrillated Cellulose and Xyloglucan

Aerogels refer to a new class of materials holding air in their structure. They are highly porous solids having a large inner surface area. They are extremely light, low heat conductive, and high sound absorbent materials. Therefore, aerogels have excellent performance in applications such as heat insulators, particle filters, particle trappers, and catalyst carriers 1 . Aerogels are prepared s...

Mechanism for Tuning the Hydrophobicity of Microfibrillated Cellulose Films by Controlled Thermal Release of Encapsulated Wax

Although films of microfibrillated cellulose (MFC) have good oxygen barrier properties due to its fine network structure, properties strongly deteriorate after absorption of water. In this work, a new approach has been followed for actively tuning the water resistance of a MFC fiber network by the inclusion of dispersed organic nanoparticles with encapsulated plant wax. The modified pulp suspen...

Water Vapor Barrier Properties of Coated and Filled Microfibrillated Cellulose Composite Films

Microfibrillated celluloses (MFCs) have mechanical properties sufficient for packaging applications but lack water vapor barrier properties in comparison to petroleum-based plastics. These properties can be modified by the use of mineral fillers, added within the film structure, or waxes, as surface coatings. In this investigation it was determined that addition of fillers resulted in films wit...
