Study on Biodegradable Starch/OMMT Nanocomposites for Packaging Applications
Journal of Polymers and the Environment - Tập 17 - Trang 203-207 - 2009
Penggang Ren, Tingting Shen, Fang Wang, Xing Wang, Zhengwei Zhang
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...... hiện toàn bộ
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
Behzad Kord, Pouria Ravanfar, Nadir Ayrilmis
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...... hiện toàn bộ
Enhancing the Oil Adsorption Properties of Cellulose Nanofiber Aerogels Through Chemical Modification
Journal of Polymers and the Environment - - Trang 1-10 - 2023
Sara Sadat Fazel, Mehdi Jonoobi, Kambiz Pourtahmasi, Sima Sepahvand, Alireza Ashori
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...... hiện toàn bộ
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
Patrícia Moraes Sinohara Souza, Nádia Aline Corroqué, Ana Rita Morales, Maria Aparecida Marin-Morales, Lucia Helena Innocentini Mei
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...... hiện toàn bộ
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
Thanaphorn Rakkan, Nisa Paichid, Kanokphorn Sangkharak
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...... hiện toàn bộ
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
R. Petrucci, E. Fortunati, D. Puglia, F. Luzi, J. M. Kenny, L. Torre
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...... hiện toàn bộ
Effect of Matrix–Particle Interfacial Adhesion on the Mechanical Properties of Poly(lactic acid)/Wood-Flour Micro-Composites
Journal of Polymers and the Environment - Tập 17 - Trang 83-94 - 2009
Eustathios Petinakis, Long Yu, Graham Edward, Katherine Dean, Hongsheng Liu, Andrew D. Scully
The influence of interfacial matrix/particle adhesion on the mechanical properties of poly(lactic acid) (PLA) micro-composites was investigated. The tensile strength of PLA/wood-flour micro-composites is almost independent of wood-flour content, suggesting only weak adhesion exists between the PLA matrix and the wood-flour particles. The addition of wood-flour resulted in an increase of up to 95% ...... hiện toàn bộ
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
Shanshan Zhou, Yongyan Sun, Huimin Ma, Chunfeng Jia, Xiaoyu Sun, Yubin Yang, Juan Liu, Jinjun Yang
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, ...... hiện toàn bộ
