Yes, as the frequency increases, the storage modulus typically increases at elevated temperatures in Dynamic Mechanical Analysis (DMA). The storage modulus, also known as the elastic modulus or the modulus of stiffness, represents the ability of a material to store energy elastically. At elevated temperatures, the polymer chains in a material become more flexible and have increased mobility, leading to enhanced viscoelastic behavior. As the frequency of the applied oscillating stress or strain increases, the polymer chains have less time to relax between cycles, resulting in a higher resistance to deformation and a larger storage modulus. This behavior is often observed in materials undergoing glass transitions or other structural transitions at elevated temperatures, where the increased mobility and energy storage contribute to the higher storage modulus values with increasing frequency.
To add to what Samira Akter Tumpa said above, this is covered by time-temperature superposition and the WLF theory, quite well described by Wikipedia (https://en.wikipedia.org/wiki/Time%E2%80%93temperature_superposition).
This is widely used to predict the high frequency behaviour of rubbers, collecting data over a range of temperatures and shifting it onto the frequency plane.
