Special Issue Information

Dear Colleagues,

This Special Issue of Polymers, titled "Inorganic Filler-Based Polymeric Composites for Enhanced Mechanical and Thermal Properties", aims to present the latest advancements in the design, synthesis, and characterization of polymer composites reinforced with inorganic fillers. The incorporation of inorganic materials such as silica, alumina, carbonates, metal oxides, layered silicates, and hybrid nanoparticles into polymer matrices has proven to be an effective strategy for enhancing mechanical strength, thermal stability, dimensional integrity, and functional performance.

This Special Issue invites original research articles and reviews that explore filler surface modification, interfacial interactions, dispersion techniques, and processing innovations that contribute to performance improvements. Contributions addressing structure–property relationships, modeling, and application-oriented studies, including those relevant to automotive, aerospace, electronics, energy, and packaging, are highly encouraged.

By bringing together interdisciplinary studies in materials science, polymer chemistry, and nanotechnology, this Special Issue aims to offer valuable insights into the development of next-generation polymer composites with superior multifunctional properties.

Abstract
This study presents the design and fabrication of silicone–urethane hybrid foam (SUF) to improve fire safety in transportation seating. Tin(II) 2-ethylhexanoate (Sn(OCT)2) was used to catalyze reactions between bifunctional isocyanates, polyols, and vinyl-terminated PDMS, enabling simultaneous curing and foaming. Sn(OCT)2 [...] Read more.
This study presents the design and fabrication of silicone–urethane hybrid foam (SUF) to improve fire safety in transportation seating. Tin(II) 2-ethylhexanoate (Sn(OCT)2) was used to catalyze reactions between bifunctional isocyanates, polyols, and vinyl-terminated PDMS, enabling simultaneous curing and foaming. Sn(OCT)2 effectively facilitated both the foaming and gelation processes of silicone and urethane chemistries. The resulting SUF demonstrated a 44.55% reduction in peak heat release rate (PHRR) compared to UF, due to the PDMS network’s synergistic flame-retardant and barrier effects. Additionally, the crosslinked PDMS structure maintained strong mechanical integrity. This study offers a simple and effective approach for producing SUF with enhanced fire safety. Full article
