ENERGY EFFICIENT NANOCELLULOSE SHEETS FOR PRODUCT APPLICATION

Synthetic polymer and plastics which are currently used as barrier materials in the packaging industry neither renewable nor biodegradable, creating a serious threat to ecosystem. Nano cellulose is obtained by breaking down fibers into nano-scale dimensions has unique properties with potential dramatically impact many commercial markets including packaging. This research investigates refining of fiber produce sustainable nano using laboratory PFI mill industrial Disc refiner. Refined pulp was made sheets standard paper making technique through vacuum filtration. The tensile index sheet density for refined BEK NBSK showed approximately five times two improvement over unrefined respectively highlighting role improving mechanical structure sheets. strength enhancement comes at cost 17417 kWh/t specific energy lab-scale 3346.3 industrial-scale refining. Fines generation result decreased porosity 37.972% 48.939% improved water vapor oxygen permeability. Refining permeability ten both them very comparable synthetic polymers such polyethylene (PE). lowest value achieved 0.533±0.098 0.762±0.03 (cc.µm)/(m2.day.kPa) competitive that plastics. Additionally, surface roughness 77.05% 52.8% promises an excellent tool smooth printed electronics applications.
