The present work shows the suitability of using industrial fluting papers as raw material for the development of four different substrates, enzymatically refined and/or containing cellulose nanofibers (CNF) in bulk. These four substrates were deeply studied and treated with different coating formulations, containing CNF, polyvinyl alcohol (PVA), native starch and alkyl ketene dimer, with the purpose...
Atmospheric pressure plasma treatment was evaluated as a desizing aid for the removal of polyvinyl alcohol from polyester/cotton fabric. The effect of plasma gas mixture and plasma duration was examined using helium gas with fractions of oxygen and carbon tetrafluoride, and for plasma exposures ranging from 0.5–10 min. The percent desizing was measured for samples exposed only to plasma, and for samples...
Efficient, rapid removal of oil spills on the surface of water is technologically significant for protecting the ecological marine environment. In this work, environmentally friendly, novel, magnetic hydrophobic PVA/CNF aerogels (MHPCA) with ultralow density (13.84 kg m−3), high porosity (> 98%), magnetic responsivity and good mechanical properties were successfully prepared by vacuum freeze-drying...
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...
This paper aims at a better understanding of the systematic production of the ethyl cellulose (EC) particles by using an emulsification-solvent evaporation method in the presence of different polysaccharide derivatives. In particular, the role of different surface active polymers i.e. one ionic—carboxymethyl cellulose, one nonionic—hydroxyethyl cellulose, and two amphiphilic—high molecular weight...
