The Center National for Evaluation of Photoprotection (CNEP), also known as the National Institute for the Evaluation of Photoprotection, is a French research center dedicated to the study and analysis of plastic materials, including identification of failure mechanisms and study of material durability.[1]
Overview edit
The center's research specializes in improving the safety and effectiveness of plastics in various applications. Key methods include conducting physicochemical analyses to determine the causes of material failures. A significant part of this process involves the use of both artificial and natural aging tests to predict the long-term performance and stability of these materials. This research plays an essential role in enhancing the reliability and safety of polymer-based products, including nanocomposite and composite materials with polymer matrices.
History edit
The National Institute for the Evaluation of Photoprotection is a subsidiary of Blaise Pascal University and was created in 1986 by Professor Jacques Lemaire, former head of the Laboratory of Molecular and Macromolecular Photochemistry (LPMM) [2]. Initially, the center's goal was to transfer LPMM's research on polymer photoaging to industrial companies facing increasing problems of plastic degradation, such as yellowing and bleaching. [2]
The center remains associated with LPMM and various companies across the field of polymer applications.[3] CNEP utilizes several tools for the physicochemical analysis of polymer material degradation, including infrared and UV-Visible spectroscopy. The center serves as an interface between polymer producers, transformers, and constructors. Additionally, CNEP is developing expertise in the analysis of organic material involved in works of art[4][better source needed] as well as the determination of common initial properties of polymers.[5]
