Polylactic acid composites incorporating casein functionalized cellulose nanowhiskers
BACKGROUND Polylactic acid (PLA) is considered to be a sustainable alternative to petroleum-based polymers for many applications. Using cellulose fiber to reinforce PLA is of great interest recently due to its complete biodegradability and potential improvement of the mechanical performance. However, the dispersion of hydrophilic cellulose fibers in the hydrophobic polymer matrix is usually poo...
متن کاملProduction and Evaluation of Biodegradable Composites Based on Polyhydroxybutyrate and Polylactic Acid Reinforced with Short and Long Pulp Fibers
In this study, two biodegradable polymers, polylactic acid (PLA) and polyhydroxybutyrate (PHB), were mixed with short and long fiber pulps using a torque rheometer. PLA/PHB-fiber composites consisting of up to 40 wt% paper pulp were produced through a unique procedure and evaluated using various techniques including thermogravimetric analysis (TGA), scanning electron microscopy (SEM), X-ray dif...
متن کاملProperties of polylactic acid composites reinforced with oil palm biomass microcrystalline cellulose.
In this work, polylactic acid (PLA) composites filled with microcrystalline cellulose (MCC) from oil palm biomass were successfully prepared through solution casting. Fourier transform infrared (FT-IR) spectroscopy indicates that there are no significant changes in the peak positions, suggesting that incorporation of MCC in PLA did not result in any significant change in chemical structure of P...
متن کاملCellulose-reinforced Composites: From Micro-to Nanoscale
This paper present the most relevant advances in the fields of: i) cellulose fibres surface modification; ii) cellulose fibres-based composite materials; and iii) nanocomposites based on cellulose whiskers or starch plateletlike nanoparticles. The real breakthroughs achieved in the first topic concern the use of solvent-free grafting process (plasma) and the grafting of the matrix at the surfac...
متن کاملProcessing and Characterization of Cellulose Nanocrystals/Polylactic Acid Nanocomposite Films
The focus of this study is to examine the effect of cellulose nanocrystals (CNC) on the properties of polylactic acid (PLA) films. The films are fabricated via melt compounding and melt fiber spinning followed by compression molding. Film fracture morphology, thermal properties, crystallization behavior, thermo-mechanical behavior, and mechanical behavior were determined as a function of CNC co...
