Summary: Stretchable conducting materials are important for unobtrusive wearable electronic devices. Electrically conducting elastomeric blend fibers with high stretchability, wet-spun from a blend of doped polar polythiophene and polyurethane, demonstrate record properties for conjugated polymer-based fibers. These fibers exhibit high cyclic stability and retain their electrical conductivity even after repeated strain cycles.

Summary: This article describes a design strategy for electronic materials using conducting polymers that can dynamically adapt to deformation rates. By utilizing interconnected nanoscopic core-shell micelles, the shells retain material integrity under strain while the cores control the extent of elongation, adapting to deformation rates. A prototype based on polyaniline showed significant increases in ultimate elongation and toughness at increasing deformation rates. This concept can be applied to create self-protective soft electronic materials with enhanced durability.

Summary: In this work, PHBV composites were prepared using TEC as a biodegradable plasticizer and SBF as reinforcement via melting extrusion. TEC reduced the viscosity and thermomechanical degradation of PHBV, while SBF acted as a nucleation agent for PHBV crystallization and enhanced the tensile properties of the matrix. TEC and SBF had antagonistic effects on the properties of the composites, providing opportunities for property tuning by varying the composition.

Summary: Wet spinning of polyacrylonitrile-based polymers is a common technique to manufacture carbon fiber precursors. Understanding the role of stretch profile on structural evolution will support efforts to reduce cost and improve process robustness. Fiber stretch generally occurs in three sequential stages: jet stretch, wet stretch (first draw), and hot draw (second draw). In this study, total fiber stretch was kept constant, but distributed differently across the stretch stages yielding three different fiber variants. Samples were collected and analyzed after each stretch stage in order to correlate process parameters to structural information. For all variants, orientation of the ordered phase increases gradually for each stage of stretch while activation energy for the structural relaxation decreases. Alternatively, crystallite size increases substantially during hot draw, which is shown to have the most pronounced effect on cyclization behavior. Given the process conditions, the variant with the lowest jet stretch and highest hot draw demonstrates the highest tenacity and modulus along with the greatest orientation, crystallite size, and highest peak exotherm temperature.

Summary: Sesbania aculeata (Dhaincha) fiber, a lignocellulosic bast fiber with a natural lignin content of about 19%, has been explored for its UV-blocking properties. Blended yarns of different linear densities and blend ratios were used to prepare woven fabrics for measuring UV protection ability, drying rate, and thermal conductivity. The optimal levels of these parameters were determined using a response surface design. The fabric achieved high UV protection factor (UPF), drying rate, and thermal conductivity of 92.68, 0.3589 ml/H, and 0.185754 W/mK, respectively. FTIR study confirmed the presence of lignin in jute and dhaincha fibers. This research work establishes a new application of dhaincha fiber in textiles for UV protection and thermal comfort.

Summary: This article examines the effects of stabilising overfeed (SOF) on the physical properties and structure of draw-texturised polyester yarn. The experiment uses partially oriented (POY) polyester filament yarn as the starting material and subjects it to texturing treatment with varying levels of SOF percentage. The measurements and analysis of various characteristics and properties of the texturised yarn samples reveal the impact of SOF% on the physical properties and structural changes of the resulting yarns. The bulk and physical structure of the yarns are assessed through optical microscopy images, while the tensile properties, thermal behavior, thermal degradation and stability, and crystallinity are evaluated using different instruments.

Summary: Polypyrrole (PPy) is widely used as a conductive polymer for conductive textile applications due to its excellent properties such as electrical conductivity, electromagnetic shielding, and anti-bacterial properties. However, its potential as a thermoelectric material has not been fully explored. This study successfully coated PPy onto cotton fabric using an in situ chemical polymerization method. The resulting PPy-coated cotton fabric exhibited good thermoelectric performance comparable to other expensive conductive polymers and inorganic semiconductors. The surface morphology, chemical interaction with cotton, semi-crystalline structure, and thermal degradation of the fabric were also analyzed.
