DEVELOPMENT, EVALUATION & OPTIMISATION OF CO2-BASED TREATMENTS FOR PLASTIC OBJECTS                                                                                                                  

Objectives:
In WP2, extensive trials will be carried out on the mock-up samples using CO2 at different conditions. The CO2 technology will be tailored for either cleaning or consolidation treatments for the selected plastic materials. Samples are characterised before, after trials and over time, to evaluate the impact of CO2 on the selected plastics, and its efficacy as a conservation strategy. 
The assessment includes empirical observations and data collected from several analytical techniques to guarantee a full characterisation of the samples from the macroscale to the nanoscale. In particular, changes in the visual appearance of the samples (dimensions, colour, gloss, surface texture), as well as modifications on their physical-chemical and mechanical properties, will be monitored.

Tasks:
Task 2.1 - Assessment of the short-long term impact of CO2 (at different conditions) on the selected plastic materials.

Task 2.2 - Evaluation of the efficacy of CO2-based treatments.

Task 2.3 - Comparison with traditional conservation treatments for plastic objects.
