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.[1] Its focus lies in understanding the durability and identifying the failure mechanisms in these materials, which are primarily composed of polymers.
Overview edit
The center's research specializes in the safe and effective use of plastics in various applications. Key methods include conducting detailed 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 in everyday and industrial uses, including nanocomposite and composite materials with polymer matrix.
History edit
The National Institute for the Evaluation of Photoprotection is a subsidiary of the University Blaise Pascal, and was created in 1986 by Professor Jacques Lemaire, former head of the Laboratory of Molecular and Macromolecular Photochemistry [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]
Today, the center remains associated with LPMM, as well as 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]
