Structure and Crystallization of Even–Odd Nylons Derived from Pimelic Acid: Influence of the Number of Methylene Groups in the Diamine Unit

open access: yesFibers
Nylons 6,7, 8,7 and 10,7 have been synthesized by interfacial polycondensation and characterized. Thermal properties and thermally induced structural transitions have been evaluated to complement the reported data on nylon 4,7.

Dielectric and Piezoelectric Properties of Nylon 9 and Nylon 11 [PDF]

open access: yesPolymer Journal, 1986
Various specimens of nylon 9 and nylon 11 were prepared, and their crystalline structures, the temperature and frequency dependences of electric properties were investigated. Dielectric constants (at 10 Hz).of various specimens were about 2.5—3 in the temperature range from −160°C to room temperature, and they began to increase near Tg and reached ...

Catalytic Autoxidation for Depolymerization of Multilayer Plastic Films

open access: yesChemSusChem, Volume 19, Issue 7, 14 April 2026.
Catalytic autoxidation using a Co/Mn/Br catalyst system depolymerizes diverse polymers in multilayer plastic films, generating oxygenated small molecules such as dicarboxylic acids. The method tolerates additives and disrupters and converts up to 48 mol% polymer carbon into soluble products, enabling chemical recycling of complex plastic waste ...

Multifunctional Electrospun Phase Change Material Mats for Solar–Thermal Energy Storage and Photothermal Conversion

open access: yesSmall Science, Volume 6, Issue 4, April 2026.
Electrospun polyester‐based phase change mats were functionalized with biochar, graphene, or polypyrrole to enhance photothermal performance. The composites maintain fibrous morphology while achieving tunable mechanical, thermal, and electrical properties. Polypyrrole‐coated mats show significantly improved light‐to‐heat conversion, demonstrating their
