Prediction of cellulose micro/nanofiber aspect ratio and yield of nanofibrillation using machine learning techniques

Abstract

inputs were chosen among these easily controlled or measured variables: Total lignin (wt%), Cellulose (wt%), Hemicellulose (wt%), Extractives (wt%), HPH Energy Consumption (kWh/kg), Cationic Demand (µeq/g), Transmittance at 600 nm and Consistency index (Ostwald-De Waele's k). In both cases, the ANN models trained here provided satisfactory estimates of aspect ratio (MAPE = 4.54% and R 2 = 0.96) and the yield of nanofibrillation (MAPE = 6.74% and R 2 = 0.98), being able to capture the effect of the applied energy along the fibrillation process. RF and LR models resulted in correlation coefficients of 0.93 and 0.95, respectively, for aspect ratio, while for yield of nanofibrillation the correlation coefficients were 0.87 and 0.92.

Hybrid Metal Oxide (Ag–ZnO) Impregnated Biocomposite in the Development of an Eco-Friendly Sustainable Film

“…8 Cellulose is a sustainable biomolecule and natural polymer available abundantly that improves the hydrogen bonding that increases the surface area of the packaging film. 9 Curcuma peel powder (CPP) contains curcumin which has a high percentage of polyphenols that enhance antimicrobial, antitumor, antioxidant, anti-inflammatory, and pH-sensitive properties that are very important in many industries. 10 Agrowaste citron leaves are fibrous and rich in ascorbic acid (44.3%/g) that enhances digestion in humans and has inherent properties in food packaging.…”

Comparative study of evolutionary machine learning approaches to simulate the rheological characteristics of polybutylene succinate (PBS) utilized for fused deposition modeling (FDM)

“…Using the same techniques, the aspect ratio and yield of nanofibrillation were predicted by Signori-Iamin, Santos, Corazza, Aguado, Tarrés and Delgado-Aguilar [29] to monitor cellulosic pulp fibrillation. They stated that the applied methods estimated the variables with high satisfaction.…”
