Abstract

This data contains diffusion measurements of Shape Memory Polymers (SMP) immersed in demineralized water. The SMP is a polyurethane-based Polymer, which is produced from SMP Technologies Inc.The SMP filament were processed with a 3D printer (Ultimaker 3, Ultimaker, Geldermarsen, Netherlands).The samples were dried in a drying oven for 10 days prior to the absorption measurements. The determination of the water absorption capacity is carried out at two different temperatures (30 °C and 60 °C). The samples are immersed in a demineralized water bath, which is stored in a drying oven. The time-dependent diffusive process is carried out with weight gain measurements.At each measuring point, the sample is taken out of the water bath and the surface water is wiped off with a lint-free cloth. Attention was paid to keep the measuring time (t < 30 sec) at each measuring point as short as possible in order not to influence the diffusive process.The measurement interval was set at the beginning of the measurement at 30 °C to 60 min and at 60 °C to 10 min. It was measured at daytime and working hours. After the samples have been completely saturated, the desorption experiment starts. The saturated samples were stored in a drying oven at 30 °C and the weight loss was measured. The measurement parameters correspond to the absorption measurements at 30 °C.
