Abstract
The production of bio-based polymers as replacements for fossil-based ones is becoming increasingly important to the human society due to the decreasing availability of fossil resources combined with rising fuel prices, and their potential to reduce greenhouse gas emissions that are the main cause of climate change. There is strong societal and regulatory pressure for the development of more sustainable biodegradable bioplastics. Viable recycling options are still lacking for many of these plastics. Due to the novelty of biodegradable bioplastics valuable chains, more research is required to reduce technical and economic uncertainties and demonstrate the feasibility and economic competitiveness of them. Therefore, there is an urgent need for technology development and the design of transition paths towards structural changes in polymers establishing local and regional circular production of bioplastics with potential impact on global economies.
It is essential to understand the factors that control the environmental behavior and fate of such bioplastics as well as their impact on ecosystem functioning. Extensive studies with accurate measurement tools and specialized analytical techniques are needed for this purpose. The radiolabeling technique (14C) allows the quantification of the degradation process of biopolymers by easily being able to distinguish between CO2 which is produced during degradation polymers and other carbon sources in natural environment.
This review provides an overview of the application of the 14C-labeling technique in polymer degradation studies that is compared under various conditions. In following, standard methods for 14C-labeling, as well as its potentials, obstacles, and deficiencies in usage, are also discussed.
期刊介绍：
Polymer Degradation and Stability deals with the degradation reactions and their control which are a major preoccupation of practitioners of the many and diverse aspects of modern polymer technology.
Deteriorative reactions occur during processing, when polymers are subjected to heat, oxygen and mechanical stress, and during the useful life of the materials when oxygen and sunlight are the most important degradative agencies. In more specialised applications, degradation may be induced by high energy radiation, ozone, atmospheric pollutants, mechanical stress, biological action, hydrolysis and many other influences. The mechanisms of these reactions and stabilisation processes must be understood if the technology and application of polymers are to continue to advance. The reporting of investigations of this kind is therefore a major function of this journal.
However there are also new developments in polymer technology in which degradation processes find positive applications. For example, photodegradable plastics are now available, the recycling of polymeric products will become increasingly important, degradation and combustion studies are involved in the definition of the fire hazards which are associated with polymeric materials and the microelectronics industry is vitally dependent upon polymer degradation in the manufacture of its circuitry. Polymer properties may also be improved by processes like curing and grafting, the chemistry of which can be closely related to that which causes physical deterioration in other circumstances.
