Abstract The attention to pursuing biodegradable fillers as reinforcement in three‐dimensional (3D) printing filament and enhancing interlayer adhesion has led the exploitation of agricultural biomass. In this study, organosolv lignin can act aforementioned twofold purposes preparing acrylonitrile butadiene styrene (ABS) for fused deposition modeling (FDM). polymer composites were homogenized with graphene nanoplatelets (GnPs) a reinforcer. Essentially, ABS 3D at 90 o shows significant...

Abstract The recognition of cellulose nanofibrils (CNF) in the past years as a high prospect material has been prominent, but impractical extraction method from biomass remained technological barrier for industrial practice. In this study, telescopic approach on fractionation lignin and was performed by organosolv catalytic oxidation oil palm empty fruit bunch fibers. integration these techniques managed to synthesize CNF short time. Aside size, zeta potential measured at −41.9 mV, which...

Cellulose was extracted from kenaf core powder by a series of bleaching processes and subsequently dissolved using an alkaline LiOH/urea solvent at low temperatures. The produced cellulose solution mixed with polyvinyl alcohol (PVA) different ratios cellulose/PVA coagulated to produce regenerated transparent films. films were then air dried film. effects PVA content on tensile index, transparency, pore size, printability the studied. A slight reduction 7% index film observed when increased...

The physico-mechanical and chemical properties of enzyme retting kenaf shredded empty fruit bunch oil palm fibres (EFB) were analyzed by extraction, microscopic, spectroscopic, thermal X-ray diffraction method.Polypropylene (PP), a petroleum based fibre, was also included to compare the synthetic fibre with natural fibres.Chemical extraction analysis showed that cellulose major component in both EFB which are 54% 41.34%, respectively.Silica content 5.29% higher than 2.21%.The result...

Recently, various electronic devices have been developed to meet the requirements of higher frequency technology applications. This widely used application without realizing has created more electromagnetic interference pollution that is harmful human health and other equipment. Therefore, research interest focuses on fabricating (EM) wave absorbing materials can absorb EM interference. In this regard, highlights use Iron Oxide Cobalt as catalyst synthesize hybrid CNT by using Thermal Vapor...

The factors responsible for the low solubility percentage of oil palm empty fruit bunch (OPEFB) cellulose pulp compared to kenaf when dissolved in aqueous NaOH/urea solvent system was reported. Physical and chemical properties both cellulose were studied compared terms lignin content, viscosity average molecular weight (Mη), crystallinity index (CrI), structure their zero span tensile strength. both OPEFB and kenaf characterized using high powered microscope field emission scanning...

Regenerated cellulose film with better mechanical properties was successfully produced by introducing aldehyde crosslinker during the regeneration process.The source material derived from kenaf core powder and dissolved in LiOH/urea solvent at -13 °C to form a solution.The solution cast coagulated bath different percentages of glutaraldehyde (GA) glyoxal (GX) regenerated film.According Fourier transform infrared spectroscopy (FTIR) spectra, hydroxyl group reduced, reducing percentage...

Nanocellulose, a refined form of cellulose, can be further functionalized on surface-active sites, with catalyst as regenerative agent. Newly developed adsorbents are expected to have the characteristics good and rapid adsorption performance regeneration properties flexible structure using 3D printing technology.
