Abstract
The development of green polymers is a crucial long-term solution to address the problem of plastic waste. In particular, the bio-based polymer polyethylene vanillic (PEV) has garnered interest due to its comparable mechanical and thermal properties to polyethylene terephthalate (PET), a widely used single-use plastic. Molecular dynamics (MD) simulations are commonly employed to study the molecular structure and dynamic properties of materials, offering cost-effective applications. However, the accuracy of MD simulation results heavily relies on the chosen force field model. The all-atom (AA) force field, while providing insights into molecular interactions, demands significant computational resources, especially for large systems like polymers. This study aimed to employ the united atom (UA) model with revised OPLS-UA force field parameters for the biopolymer PEV, aiming to reduce computational time in dynamic and physical investigations. Consequently, the UA model successfully folded the PEV polymer in a manner resembling the single-chain PEV treated with the AA model, while also predicting a glass transition temperature (Tg) close to the experimental value of 348 K. These findings underscore the potential of the UA model for simulating PEV and its promising implications.
期刊介绍:
The Chiang Mai Journal of Science is an international English language peer-reviewed journal which is published in open access electronic format 6 times a year in January, March, May, July, September and November by the Faculty of Science, Chiang Mai University. Manuscripts in most areas of science are welcomed except in areas such as agriculture, engineering and medical science which are outside the scope of the Journal. Currently, we focus on manuscripts in biology, chemistry, physics, materials science and environmental science. Papers in mathematics statistics and computer science are also included but should be of an applied nature rather than purely theoretical. Manuscripts describing experiments on humans or animals are required to provide proof that all experiments have been carried out according to the ethical regulations of the respective institutional and/or governmental authorities and this should be clearly stated in the manuscript itself. The Editor reserves the right to reject manuscripts that fail to do so.
