Project Title
The role of plasticiser loss in the degradation of plastic objects in heritage collections
Background & Summary of Project
From our childhood toys to modern art, plastics are prevalent in collections used to record our heritage. However, plastics wear out; becoming discoloured and deformed due to a variety of decay processes involving the polymer and additives used to manufacture the plastic. My background in chemistry now allows me to study the degradation of cellulose acetate and PVC objects, with a particular focus on how the object's physical properties and surrounding environment influence the rate of plasticiser loss.
