High Removal Capacity of Arsenic from Drinking Water Using Modified Magnetic Polyurethane Foam Nanocomposites
Journal of Polymers and the Environment - Tập 27 - Trang 1497-1504 - 2019
In this study, a novel polyurethane foam (PU) nanocomposite adsorbent based on silane-modified magnetic iron-oxide nanoparticles (Fe3O4@APTES) is synthesized via a low cost and simple in situ polymerization method for the removal of arsenic ions from aqueous solutions. The chemical structure and surface morphology of the prepared nanoparticles and adsorbent were characterized using Fourier transfo...... hiện toàn bộ
Cellulose acetate biodegradability upon exposure to simulated aerobic composting and anaerobic bioreactor environments
Journal of Polymers and the Environment - Tập 1 - Trang 143-153 - 1993
Cellulose acetate (CA) films with degree of substitution (d.s.) values of 1.7 and 2.5 were exposed to biologically active in-laboratory composting test vessels maintained at approximately 53 °C. The CA 1.7- and 2.5-d.s. films (thickness values of ∼0.5–1.0 and 2.0 mil, respectively) had completely disappeared by the end of 7- and 18-day exposure time periods in the biologically active bioreactors, ...... hiện toàn bộ
Dispersion and Reinforcing Potential of Carboxymethylated Nanofibrillated Cellulose Powders Modified with 1-Hexanol in Extruded Poly(Lactic Acid) (PLA) Composites
Journal of Polymers and the Environment - Tập 20 - Trang 1052-1062 - 2012
Bionanocomposites of poly(lactic acid) (PLA) and chemically modified, nanofibrillated cellulose (NFC) powders were prepared by extrusion, followed by injection molding. The chemically modified NFC powders were prepared by carboxymethylation and mechanical disintegration of refined, bleached beech pulp (c-NFC), and subsequent esterification with 1-hexanol (c-NFC-hex). A solvent mix was then prepare...... hiện toàn bộ
Experimental Design to Optimize the Extraction and Properties of an Alternative Gum from Crotalaria Juncea Seeds

Evaluation of Active PBAT Films Incorporated with Orange Essential Oil Biodegradation in Anaerobic Biodigesters
Journal of Polymers and the Environment - Tập 31 - Trang 3814-3824 - 2023
The use of biodegradable polymers applied in active packaging systems, where additives are incorporated that aim to extend the shelf life of foods, is a promising topic in the search for ecologically correct materials. However, it is not known whether in these systems, the presence of the antimicrobials additive, will exert a negative influence on the biodegradation process of this polymeric mater...... hiện toàn bộ
A Pragmatic Review on Bio-polymerized Metallic Nano-Architecture for Photocatalytic Degradation of Recalcitrant Dye Pollutants
Journal of Polymers and the Environment - - Trang 1-30 - 2023
Clean water is a prerequisite for health living and smooth eco-fundamental networking. However, the dye industry which is contributing remarkably to the world economic growth is equally contributing to the drastic reduction in the availability of clean water and this has become a global challenge. Notably, conventional methods and materials have been used to remove dye pollutants, but they encount...... hiện toàn bộ
Novel Biorenewable Composites Based on Poly (3-hydroxybutyrate-co-3-hydroxyvalerate) with Natural Fillers
Journal of Polymers and the Environment - Tập 27 - Trang 803-815 - 2019
Due to the ubiquity and single-use character of plastic products, their production represents a burden to the environment. Therefore, an increasing interest in biodegradable and bio-compostable materials has been observed in the recent years. Bio-based materials are becoming more and more popular, especially in applications where biodegradability provides an advantage for customers and environment...... hiện toàn bộ
Enhanced Performance of Aloe vera-Incorporated Bacterial Cellulose/Polycaprolactone Composite Film for Wound Dressing Applications
Journal of Polymers and the Environment - Tập 30 - Trang 1151-1161 - 2021
Recently, biopolymers have become a resource for the biomedical material field due to its biocompatibility and biodegradability. In this work, Aloe vera-loaded bacterial cellulose- and polycaprolactone -based composites were successfully prepared for wound dressing applications. The structural, morphological, thermal, swelling, and degradation properties were investigated. Result showed that the a...... hiện toàn bộ
Candida antarctica Lipase B as Catalyst for Cyclic Esters Synthesis, Their Polymerization and Degradation of Aliphatic Polyesters
Journal of Polymers and the Environment - Tập 26 - Trang 396-407 - 2017
Candida antarctica: lipase B (CALB) is the most widely studied enzyme, due to its high selectivity and catalytic activity in organic and polymer synthesis. To avoid organometallic catalysts in the synthesis of biodegradable polyesters, the enzymatic ring-opening polymerization of cyclic esters can be carried out with CALB as a biocatalyst. This paper reviews selected examples of the application o...... hiện toàn bộ
