Project Title 

From Samples to Complex Objects: Detecting Material Degradation in Plastic Artworks (Nanorestart)

Background & Summary of Project

Research into the decay of modern materials found in heritage environments is a rapidly growing area within heritage science. This is due to the rapid and often catastrophic decay suffered by many commonly found polymers. Consequently, the need for accurate and reliable conservation treatments or monitoring programs are much needed. This project will exploit the information gained from the volatile organic compounds (VOCs) naturally emitted from polymers with the aim to detect and monitor the decay of 3D artworks on open display or housed in storage environments. Laboratory work (both at UCL and Arkema) will focus on developing an experimental method using solid-phase micro extraction gas chromatography mass spectrometry (SPME-GCMS); this methodology will then be implemented in the real-world heritage environment of the project’s heritage partner Tate.
