Abstract Scope |
Understanding chemical compatibility and aging behavior of additively manufactured (AM) silicone foams is vital to determine the impacts on mechanical performance. In this study, we investigated the absorption and outgassing of targeted organic solvents by AM silicone polymers with and without compression at two different temperatures. Preliminary data demonstrates that the AM silicone foams have a high affinity for organic solvents and readily uptake >1.5 times their mass within days under suitable conditions. These early results will inform aging studies designed to quantify the impact of solvents on properties, such as compression set and load retention, as well as chemical changes to the AM polymers.
