Special Issue Information

Dear Colleagues,

The growing demand for sustainable energy highlights the need for materials that endure extreme service conditions. High-temperature polymer nanocomposites have emerged as promising solutions, combining lightweight polymer matrices with nanoscale fillers for enhanced thermal stability and mechanical performance. Incorporating functionalized nanofillers (graphene, CNTs, BN, etc.) into high-T polymers (polyimides, epoxies, elastomers) can significantly raise storage modulus and degradation temperature, enabling polymer seals, insulators, and membranes to maintain integrity in geothermal, hydrogen, solar and other energy systems.

This special issue on “Sustainable Materials for Energy Industry: High-Temperature Polymer Nanocomposites” seeks high-quality works focusing on cutting-edge developments in this field. Topics include, but are not limited to:

  • Design and synthesis of high-temperature polymer nanocomposites using advanced polymer matrices (e.g., polyimides, PEEK, elastomers) and functional nanofillers (graphene, CNTs, boron nitride, metal oxides);
  • Innovative processing techniques such as melt compounding, in-situ polymerization, surface functionalization, and additive manufacturing to enhance nanoparticle dispersion and interfacial interactions;
  • Thermo-mechanical and chemical performance under extreme environments, including thermal stability, creep resistance, modulus retention, and degradation pathways;
  • Durability, reliability, and modeling of long-term behavior in harsh operating conditions;
  • Applications in advanced energy systems such as geothermal well sealing, hydrogen storage and transport, solar thermal components, and nuclear energy technologies;
  • Sustainable material strategies involving bio-based polymers and recyclability in high-temperature applications.

Soft contact lenses are usually characterised at room temperature, yet they function on the eye at body temperature, where their mechanics and optical performance can change. This study investigated whether soft silicone hydrogel lenses become more compliant in a physiological environment. Two silicone hydrogel materials (Definitive 74 and Unisil) were tested at 24 °C and 35 °C using uniaxial tensile and compression methods, with Ogden hyperelastic models fitted and finite element analysis performed on a realistic eye model. Both materials became more compliant at 35 °C, with Definitive 74 showing a larger modulus decrease (0.40 to 0.32 MPa) than Unisil (0.73 to 0.70 MPa). Finite element simulations indicated that these temperature-driven changes in compliance significantly affected refractive power, especially when the lens base curve exceeded the corneal radius by more than 5%. These findings demonstrate that soft silicone hydrogel lenses are indeed more compliant in a warm, hydrated environment, highlighting the need for physiologically relevant testing to inform design, fitting strategies, comfort, and vision outcomes.
