Developing green and facile synthesis techniques for biomaterials has been widely advocated recently. In this study, we report a green and facile approach to prepare pineapple peel cellulose/magnetic diatomite hydrogels in an environmentally benign ionic liquid, 1-butyl-3-methylimidazolium chloride. The structure, swelling and methylene blue (MB) adsorption of the prepared hydrogels were investigated...
The applications of polyvinyl alcohol (PVA) films are still hampered due to great affinity to water, poor mechanical strength and lack of biological properties. To overcome these shortcomings, this study presented a successful development of PVA films by the introductions of tannic acid (TA) and pineapple peel-derived cellulose nanocrystals (PPNc). The structure, morphology, light transmittance, water...
Pineapple peel is a renewable agricultural residue available in abundance whose multipurpose utilization deserves more attention. The present study aimed at the isolation of nanocellulose from pineapple peel and evaluation on its reinforcement capability for gellan gum film. The results from scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR) and X-ray diffraction (XRD)...
Natural polymers hydrogels were prepared by solution blending of gelatin, sodium alginate and carboxymethyl cellulose isolated from pineapple peel, and cross-linking with CaCl2 and glutaraldehyde solutions. The prepared hydrogels were characterized by Fourier transform infrared spectroscopy, X-ray diffraction and field emission scanning electron microscope. The swelling behaviors and responsiveness...
Novel composite hydrogels were synthesized by grafting of acrylic acid onto pineapple peel cellulose and addition of kaolin or sepia ink in ionic liquid 1-butyl-3-methylimidazolium chloride, using potassium persulfate as a free radical initiator and N,N′-methylenebisacrylamide as a crosslinking agent. The structure and morphology of the prepared hydrogels were characterized by Fourier transform infrared...
Composite hydrogels were prepared from pineapple peel cellulose with the combinations of polyethylene glycol (PEG), polyvinyl alcohol (PVA), к-carrageenan (CN), or soluble starch (SH) in 1-allyl-3-methylimidazolium chloride solvent. Impacts of these macromolecules on the texture profile analysis (TPA) parameters, equilibrium swelling ratio (ESR), and sodium salicylate (NaSA) load of the prepared hydrogels...
