Newma Showcases Its Expertise | A New Approach to Thermal Conductivity Material Characterization! Newma at the 2025 (8th) Military-Civilian Dual-Use New Materials Forum

From May 16 to 18, 2025, the 8th Military-Civilian Dual-Use Absorbing, Shielding, and Thermally Conductive New Materials Forum was grandly held in Nanjing. The forum brought together industry experts, scholars, and corporate representatives to explore cutting-edge technologies and development trends in the field of dual-use new materials.

At the forum, Niumag Product Manager, Mr. Liu, delivered an engaging presentation focusing on the innovative applications of Low-Field Nuclear Magnetic Resonance (LF-NMR) technology in thermal conductive material analysis, captivating the attending guests.

LF-NMR technology, a non-destructive method based on the magnetic properties of atomic nuclei, has recently emerged as a powerful tool in material analysis. Mr. Liu highlighted its application in particle dispersibility and specific surface area analysis. By precisely measuring the relaxation time distribution of hydrogen nuclei within materials, LF-NMR provides deep insights into microstructural features, including the dispersion state of particles and the accurate determination of their specific surface area, offering critical guidance for optimizing material performance.

Additionally, Mr. Liu shared exemplary cases of LF-NMR applied to characterising soft and hard segments in polymeric materials. In polymers, hydrogen nuclei experience varying chemical environments, resulting in distinct relaxation times. Leveraging LF-NMR, researchers can clearly differentiate soft and hard segment structures within polymers, gaining key insights into molecular chain arrangements, crosslinking density, and intermolecular interactions. Such analyses are crucial for enhancing polymer performance, especially in dual-use applications demanding high reliability and superior material properties.

Mr. Liu’s presentation generated strong interest among attendees. After the session, numerous experts and corporate representatives engaged him in detailed discussions on LF-NMR applications, including particle dispersibility characterization, specific surface area measurement, and soft-hard segment analysis in polymers.

Mr. Liu enthusiastically explained the principles of LF-NMR, the unique features of the instruments, and demonstrated a range of practical applications. The live experimental data and case studies showcased the technology’s significant advantages and wide-ranging potential for new material development and quality control.
