Rapid fabrication of sulfur-free hollow nanospheres and cellulose nanofibrils for 3D bioprinting ink applications

Statement of the Problem: The present work provides method of quick production of highly porous Nano cellulose with uniformly spherical (CNS) and fibrous (NFCs) morphology from a waste biomass. The conventional methods used for synthesis of cellulose nano spheres (especially) are so far time consuming and utilize a main hydrolysis treatment of fibrous macro and microstructures in which high concentration H2SO4, H2SO4/HCl acid or enzymatic process is followed that utilize acids with concentration up to 64%. Due to which different factors from environment to characteristic properties of individual Nano cellulose remain affected. But in this study synthesis of hollow Nano spheres involves sulphur free method along with mechanical treatment to produce CNS and NFCs directly from defibrillated MFCs of waste biomass. Methodology & Theoretical Orientation: In place of conventional methods involving high concentration acid hydrolysis (mostly mediated by sulfuric acid), a combination of physico-chemical methods was used that in addition with intrinsic properties of the raw material helped producing speedy release of nanospheres from MFCs during high shear mechanical treatment.Statement of the Problem: The present work provides method of quick production of highly porous Nano cellulose with uniformly spherical (CNS) and fibrous (NFCs) morphology from a waste biomass. conventional methods used for synthesis of cellulose nano spheres (especially) are so far time consuming and utilize a main hydrolysis treatment of fibrous macro and microstructures in which high concentration H2SO4, H2SO4/HCl acid or enzymatic process is followed that utilize acids with concentration up to 64%.
