Journal ArticleDOI
Cellulose nanocrystals: synthesis, functional properties, and applications.
Johnsy George,S. N. Sabapathi +1 more
TL;DR: This review aims to collate the knowledge available about the sources, chemical structure, and physical and chemical isolation procedures, as well as describes the mechanical, optical, and rheological properties, of cellulose nanocrystals.
Journal ArticleDOI
Bacterial cellulose nanocrystals exhibiting high thermal stability and their polymer nanocomposites.
TL;DR: The BCNC obtained through cellulose treatment under controlled conditions were associated with several desirable properties and appear to be superior over the conventional methods of nanocrystals production.
Journal ArticleDOI
High performance edible nanocomposite films containing bacterial cellulose nanocrystals
Johnsy George,Siddaramaiah +1 more
TL;DR: In this paper, the use of bacterial cellulose nanocrystals (BCNCs) in the fabrication of edible, biodegradable and high-performance nanocomposite films for food packaging applications at relatively low cost.
Journal ArticleDOI
Characterization of chemically treated bacterial (Acetobacter xylinum) biopolymer: some thermo-mechanical properties.
Johnsy George,Karna Venkata Ramana,Shanmugham Nadana Sabapathy,J. H. Jagannath,Amarinder Singh Bawa +4 more
TL;DR: The study delineated the effect of alkali treatment regimens, on the thermo-mechanical properties of bacterial cellulose for its application over a wide range of temperatures.
Journal ArticleDOI
Hybrid HPMC nanocomposites containing bacterial cellulose nanocrystals and silver nanoparticles.
Johnsy George,R. Kumar,Vallayil Appukuttan Sajeevkumar,Karna Venkata Ramana,R. Rajamanickam,Virat Abhishek,Shanmugam Nadanasabapathy,Siddaramaiah +7 more
TL;DR: Moisture sorption analysis proved that the hydrophilicity of the nanocomposite decreased considerably by the addition of these nanomaterials, which is expected to be useful in eco-friendly food packaging applications.
