Optimization of wheat‐straw‐extracted cellulose via response surface methodology and mechanical properties of its poly(lactide)‐based biocomposites

Abstract

In view of environmental footprints and growing demand for green energy materials, employing biomass by eliminating lignin and hemicellulose has been topic of recent interests due to their applications in food packaging, textile, automobile, and polymer industries. Herein, we report on optimization of the cellulose extraction (removal of lignin and hemicellulose) from agro-waste (wheat straw) by the response surface methodology (RSM), where, the Box Behnken Design has been implemented to study the effect of sodium hydroxide/sodium hypochlorite amount, temperature, and time on the extraction process. Fourier transform infrared spectroscopy, X-ray diffraction study, and thermal degradation analysis indicate the successful isolation of cellulose with maximum (56%) removal of hemicellulose and lignin under optimal conditions. Furthermore, nano-indenter analysis and tensile strength have been examined for cellulose/poly(lactide) biocomposites at different wt.% of cellulose, which indicated better tensile strength (28.15 MPa), tensile modulus (2430.24 MPa), and elongation at break (1.89%) as compared to intrinsic poly(lactide). Such studies on the cellulose extraction with optimized conditions and their mechanically stable biocomposites will pave the way for their utilization in polymer industrial applications.

Investigation and prediction of mechanical properties of hot water treated jute/poly(lactic acid) composite laminates using response surface methodology and genetic algorithm

“…“Adequate Precision” is the ratio of signal to noise, which is desirable for larger than 4. [ 61,62 ] Here is 24.362, demonstrating that this model can be abundantly accurate to navigate the design space. Analysis of variance (ANOVA) is utilized to determine the significant factors affecting the quality objectives, which is used to assess linear, quadratic and interaction regression coefficients in this work.…”

Cellulose from the banana stem: optimization of extraction by response surface methodology (RSM) and charaterization

“…To achieve high extraction efficiency while minimizing waste to the environment, the extraction process must be optimized. Modeling and optimization of cellulose extraction from wheat straw, maize cob, palm tree, and orange peel have been studied [ 20 , 21 , 22 , 23 ]. However, modeling and optimization of the cellulose extraction process from the banana stem aided microwave have not been described.…”
