Polymer thin film characterization at cold temperatures using nanoDMA III and xSol Cryo

Bruker Nano Surfaces and Metrology
23 Jul 2023

Polymer thin films are widely used for a variety of applications, ranging from artificial skin to anti-reflective coatings. Understanding the viscoelastic properties at various temperatures is important for ensuring engineering performance. The measurement of viscoelastic properties of polymer thin films across a range of temperatures can prove difficult in comparison to a bulk sample. In this application note from Bruker Nano, the viscoelastic properties of polymer thin films are investigated from -125°C to 23°C using dynamic nanoindentation.

NanotechnologyNanotechnology, or nanotech, is an engineering technique using molecular scale functional systems. Applications of nanotechnology include medicine and medical devices, electronics, air and water purification, food science and energy production.Thermal Analysis EquipmentThermal analysis equipment is used for measuring heat flow, weight loss, dimension changes or thermomechanical properties and is important for analyzing a material’s performance and stability. Thermal analysis equipment includes differential scanning calorimeters (DSC), thermogravimetric analyzers (TGA), thermomechanical analyzers (TMA), dilatometers, thermometers, vapor sorption analyzers, boiling and melting point apparatus. Thermal analyzers can reveal properties such as melting, crystallization and glass transitions or other processes such as oxidation, decomposition, volatilization, as well as coefficients of thermal expansion and modulus. Find the best thermal analysis equipment in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.Non-Destructive TechniquesNon-destructive techniques (NDT) describes a variety of analytical techniques used to evaluate the properties of a material. Common methods include ultrasonic, magnetic-particle, liquid penetrant, radiographic, remote visual inspection (RVI), and eddy-current testing. NDT is regularly used in forensic engineering, civil engineering, mechanical engineering, electrical engineering, systems engineering, aeronautical engineering, and medicine.ProfilometersProfilometers are instruments used to measure a surface's profile, in order to quantify etch depth, deposited film thickness, and surface roughness. They operate in either contact or non-contact modes and may use optical or stylus techniques to make the actual measurements.TemperatureNanostructures
