## Description

- description: "Characterizing the temperature-dependent mechanical properties of
    polymeric\r\nmaterials is critical for industrial applications in aerospace, automotive,
    and electronics.\r\nThe increasing integration of artificial intelligence (AI)
    in material discovery has\r\namplified the demand for large, high-quality datasets,
    which conventional mechanical\r\ntesting methods often cannot efficiently provide.
    In this study, we introduce a novel\r\nmicro-indentation method that enables rapid
    and accurate evaluation of static and\r\ndynamic mechanical properties of polymeric
    materials across a wide temperature range.\r\nThe technique enables independent
    and precise temperature control of the indenter and\r\nbulk samples, ensuring
    reliable measurements with minimal preparation. Static\r\nindentation tests on
    epoxy and acrylic samples demonstrated that the elastic modulus can\r\nbe accurately
    obtained from unloading data, even with plastic deformation, using the\r\nOliver–Pharr
    method. Dynamic testing further revealed that the epoxy exhibited higher\r\nstorage
    and loss moduli than the acrylic adhesive, indicating superior mechanical\r\nperformance
    at elevated temperatures. Conversely, the acrylic adhesive exhibited a lower\r\nglass
    transition temperature, indicating a narrower operational temperature range, and
    a\r\nhigher loss factor, reflecting greater energy dissipation. The proposed method
    enhances\r\nthe efficiency and accuracy of mechanical characterization, enabling
    the high-throughput\r\ntesting necessary to generate datasets for AI-driven material
    development. By enabling\r\nrapid design and optimization of polymers, this technique
    is promising for advancing\r\nmaterial discovery with tailored properties."
