Preparation & characterization of microcrystalline cellulose from agriculture waste [PDF]

, 2020
In this work, microcrystalline cellulose was prepared from oil palm trunk by water treated fibre process and alkali bleaching. The prepared samples were characterized by using Fourier-transform infrared spectroscopy attenuated total reflectance (FTIR-ATR)

Digital Printing of Photoreversible Protective Films

Macromolecular Rapid Communications, EarlyView.
A photopolymerized and photoreversible temporary protective film based on an ortho‐nitrobenzyl crosslinker is presented that can be applied using aerosol jet printing. To improve adhesion to industry‐relevant surfaces, a polyethyleneimine‐based adhesion promoter was added to the aqueous formulation of diacrylate cross‐linker and acrylated macromers ...

Extraction of Cellulose and Microcrystalline Cellulose from Kenaf

Jurnal Kejuruteraan, 2020
Bast and core of kenaf which categorized as agriculture residues were used in the extraction of cellulose due to its lignocellulosic nature. In this study, cellulose was extracted from the raw kenaf by using 10% alkaline peroxide pre-treatment followed by extraction process at 85 °C using the combination of 20% (v/v) formic acid and 10% (v/v) hydrogen ...

Production of Microcrystalline Cellulose by Reactive Extrusion [PDF]

, 2001
This process involves feeding cellulose into an extruder with an acid solution. The extruder is comprised of a screw and a barrel. The screw is rotated so as to pressurize the cellulose, and the cellulose undergoes acid hydrolysis and forms ...

Combined Effects of Thermal Cycling Aging and Reinforcement Content on the Ball‐On‐Disk Wear of Additively Manufactured Polylactic Acid Composites

Polymer Composites, EarlyView.
Thermal Aging and Tribological Tests of Additive Manufactured PLA Composites. ABSTRACT This study focuses on the additive manufacturing of pure polylactic acid (PLA) specimens and milled glass fiber (GF)‐filled PLA composites under thermal cycling aging and wear tests. Wear tracks have been analyzed via 3D optical profiling and SEM imaging.

Microcrystalline Cellulose Extraction in Blended Textile Waste with Preliminary Evaluation of Polyester Integrity

Applied Sciences
Mixed cotton–polyester textile waste remains difficult to recycle because processes that recover synthetic polymers often leave the cotton fraction underused, while cellulose extraction methods may compromise the polyester component.
