Special Issue Information

Dear Colleagues,

Today, the development of new nanoscale characterization techniques in combination with modern analytical methods, the investigation of the degradation phenomena and the prediction of service lifetime of polymer materials becomes easier and more efficient. New cutting edge technologies of advanced additives preparation makes polymer today becoming smarter, more sustainable and durable against chemical and physical aging agents.

Polymer materials are relative unstable under the presence of radiations and environment agents such as temperature, humidity, wind, ozone, and mechanical vibrations. They degrade too quickly to be able to maintain their functional properties for a period long enough to industrial applications intended.

The involved degradation and deterioration mechanisms polymers are quite complex depending and their chemical composition and production methods. Better understanding aging phenomena at the macroscopic and nanoscale scales and the related mechanisms could help to the prediction the service lifetime and find a suitable solution to improve the properties of polymers for various desired end-used applications.

This Special Issue aims to collect articles reporting on recent developments dealing with the polymer degradation and stability. It covers the different methods for testing, evaluating as well as mathematical methods for predicting of the polymer aging and stability.

The strong environmental impact caused by plastic pollution has led research to address studies from different perspectives. The mathematical modeling of the biodegradation kinetics of solid materials is a major challenge since there are many influential variables in the process and there is interdependence of microorganisms with internal and external factors. In addition, as solid substrates that are highly hydrophobic, mass transfer limitations condition degradation rates. Some mathematical models have been postulated in order to understand the biodegradation of plastics in natural environments such as oceans. However, if tangible and optimizable solutions are to be found, it is necessary to study the biodegradation process under controlled conditions, such as using bioreactors and composting systems. This review summarizes the biochemical fundamentals of the main plastics (both petrochemical and biological origins) involved in biodegradation processes and combines them with the main mathematical equations and models proposed to date. The different biodegradation studies of plastics under controlled conditions are addressed, analyzing the influencing factors, assumptions, model developments, and correlations with laboratory-scale results. It is hoped that this review will provide a comprehensive overview of the process and will serve as a reference for future studies, combining practical experimental work and bioprocess modeling systems.
