Study on Biodegradable Starch/OMMT Nanocomposites for Packaging Applications
Journal of Polymers and the Environment - Tập 17 - Trang 203-207 - 2009
The thermoplastic starch (TPS) and nanocomposite(TPS/OMMT) was prepared with 15% carbamide, 15% ethanolamine and different contents of organic activated montmorillonite (OMMT) by twin-screw extruder with a 130 °C barrel temperature. Fourier transforms infrared spectroscopy and wide angle X-ray diffraction shown that the alkylamine in dodecyl benzyl dimethyl ammonium bromide could react with MMT vi......
Influence of Organically Modified Nanoclay on Thermal and Combustion Properties of Bagasse Reinforced HDPE Nanocomposites
Journal of Polymers and the Environment - Tập 25 - Trang 1198-1207 - 2016
The nanocomposites of high density polyethylene (HDPE)/bagasse flour (BF) with different contents of the organomodified montmorillonite (OMMT) were produced by melt blending process. The thermal stability and combustion behavior of nanocomposites were characterized by thermogravimetric analysis (TGA), differential scanning calorimetry, and cone calorimeter tests. The results of TGA data of the nan......
Enhancing the Oil Adsorption Properties of Cellulose Nanofiber Aerogels Through Chemical Modification
Journal of Polymers and the Environment - - Trang 1-10 - 2023
The primary objective of the study was to develop a method for enhancing the oil adsorption capacity of cellulose nanofibers (CNFs) by modifying their surface. To achieve this goal, aerogels were first dried in a freeze dryer, followed by surface hydrophobization of CNFs using hexadecyltrimethoxysilane (HDTMS) as the modifier. The optimal concentration of the HDTMS for enhancing the nanofiber’s su......
PLA and Organoclays Nanocomposites: Degradation Process and Evaluation of ecotoxicity Using Allium cepa as Test Organism
Journal of Polymers and the Environment - Tập 21 - Trang 1052-1063 - 2013
In this study, nanocomposites of PLA and organoclays Cloisite 20A and Cloisite 30B were prepared by the melt intercalation method and the obtained samples were characterized by transmission electron microscopy (TEM). Since composting is an important proposal to the final disposal of biopolymers, the influence of clays on the hydrolytic degradation process of PLA was evaluated by visual analysis an......
The Integration of Methylene Blue Decolorization with Polyhydroxyalkanoate (PHA) Production Using Enterobacter Strain TS1L
Journal of Polymers and the Environment - Tập 31 - Trang 1202-1208 - 2022
The present study focused on the decolorization of methylene blue (MB) and the production of polyhydroxyalkanoate (PHA) by Enterobacter strain TS1L using PHA medium containing 50 mg/l of MB. The highest PHA production at 56.02 ± 6.26% of dry cell weight (% DCW) was observed after 24 h of cultivation, while the most effective dye decolorization at 92.57 ± 0.03% was observed after 72 h of cultivatio......
Life Cycle Analysis of Extruded Films Based on Poly(lactic acid)/Cellulose Nanocrystal/Limonene: A Comparative Study with ATBC Plasticized PLA/OMMT Systems
Journal of Polymers and the Environment - Tập 26 - Trang 1891-1902 - 2017
Life cycle analysis (LCA) of limonene plasticized poly(lactic acid) (PLA) films containing cellulose nanocrystals (CNC) extracted, by acid hydrolysis, from Phormium tenax leaf fibres, was assessed and compared with the results of acetyl tributyl citrate (ATBC) plasticized PLA films, having equivalent mechanical properties, containing organo-modified montmorillonite (OMMT). Eco-Indicator 99 tool ha......
Linear Diamides Derivative-Nucleated Biodegradable Poly(ethylene succinate) Polyester: Crystallization Kinetics and Aggregated Structure Manipulated by Hydrogen Bond Interaction
Journal of Polymers and the Environment - Tập 29 - Trang 3605-3617 - 2021
A linear diamides derivative (TMC300) as a nucleating agent (NA) was incorporated into biodegradable poly(ethylene succinate) (PES) to investigate effect of TMC300 on nucleation, crystallizability, crystallization kinetics, aggregated structure of PES. TMC300 enhanced significantly crystallizability and crystallization temperature of PES in cooling process at a rate of 10 ℃/min from molten state, ......

Microbial Degradation of UV-Pretreated Low-Density Polyethylene Films by Novel Polyethylene-Degrading Bacteria Isolated from Plastic-Dump Soil
Journal of Polymers and the Environment - Tập 26 - Trang 3613-3625 - 2018
Eleven effective low-density polyethylene (LDPE)-degrading bacterial strains were isolated and identified from landfill soil containing large amounts of plastic materials. The isolates belonged to 8 genera, and included Pseudomonas (areroginosa and putida), Sphingobacterium (moltivorum), Delftia (tsuruhatansis), Stentrophomonas (humi and maltophilia), Ochrobacterum (oryzeae and humi), Micrococcus ......
Itaconic Acid Grafted Starch Hydrogels as Metal Remover: Capacity, Selectivity and Adsorption Kinetics
Journal of Polymers and the Environment - Tập 24 - Trang 343-355 - 2016
Hydrogels were synthesized by free radical graft copolymerization of itaconic acid (IA) onto corn starch (S-g-IA). For this purpose, potassium permanganate (KMnO4)-sodium bisulfite (NaHSO3) was used as redox initiation system. The formation of grafted starches was confirmed by Fourier transform infrared spectroscopy, wide angle X-ray scattering, thermogravimetric analysis and scanning electron mic......
