Preparation of cellulose nanofibrils by high-pressure homogenizer and cellulose-based composite films

Sun-Young Lee, +3 more
- 01 Jan 2009 - 
TL;DR: In this paper, a high-pressure homogenizer was used for the preparation of cellulose nanofibrils from starting material microcrystalline cellulose (MCC) by an application of a high pressure homogenization at 20,000psi and treatment consisting of 0, 1, 2, 5, 10, 15 and 20 passes.
Journal ArticleDOI

Influence of Chemical Modification and Filler Loading on Fundamental Properties of Bamboo Fibers Reinforced Polypropylene Composites

Sun-Young Lee, +5 more
- 08 Jun 2009 - 
TL;DR: In this article, the effects of chemical modification (silane coupling) and filler loading on the fundamental properties of the bamboo fiber (BF) filled polypropylene (PP) bio-composites were investigated.
Journal ArticleDOI

Hetero-Nanonet Rechargeable Paper Batteries: Toward Ultrahigh Energy Density and Origami Foldability

Sung Ju Cho, +12 more
- 01 Oct 2015 - 
TL;DR: In this paper, a new class of hetero-nanonet (HN) paper batteries based on 1D building blocks of cellulose nanofibrils (CNFs)/multiwall carbon nanotubes (MWNTs) is demonstrated.
Journal ArticleDOI

Preparation of ultrastrength nanopapers using cellulose nanofibrils

Sang-Jin Chun, +5 more
- 25 May 2011 - 
TL;DR: In this article, the cellulose nanofibrils were used to prepare nanopapers of extremely high tensile performance and chemical modifications with the increased pass number through the homogenizer provided the dramatically increased tensile modulus and strength of the nanopapers.
Journal ArticleDOI

Physiochemical, optical and mechanical properties of poly(lactic acid) nanocomposites filled with toluene diisocyanate grafted cellulose nanocrystals

Jaegyoung Gwon, +5 more
- 25 Jan 2016 - 
TL;DR: In this paper, a chemical modification of cellulose nanocrystals (CNCs) was performed using toluene diisocyanate (TDI) to overcome the limitation of the CNCs in nonpolar solvent systems.
