Preparation of ultraviolet-cured silicone elastomer reinforced by SH-POSS crosslinker for light emitting diode encapsulant

A series of new photo-cured silicone encapsulants (SH-POSS/UVSE) have been developed through thiol-ene click chemistry. The tensile strength and elongation at break reached 1.01 MPa and 422%, respectively. When the LED sample encapsulated by it was immersed in boiling red ink for 2 h, no crack or stain was observed, indicating that it possessed good adhesion to the LED lead frame.

The effect of rubber and plastic mass ratio on the compatibilized ethylene propylene diene monomer/polypropylene TPV with shape memory behavior

The effect of mass ratio of EPDM and PP on the shape memory performance and mechanical property of TPV compatibilized by magnesium maleate and maleic anhydride was studied. The TPV obtained balanced shape memory performance at the EPDM/PP mass ratio of 70/30 and 60/40. The mechanical performance of the compatibilized TPV was improved due to the ionic interaction.

Colorimetric chitosan/polyvinyl alcohol composite membrane incorporated with anthocyanins as pH indicator for monitoring fish freshness

During storage, food undergoes various transformations, often leading to the formation of total volatile basic nitrogen (TVB-N), which is widely regarded as a reliable indicator of food freshness. The chitosan/polyvinyl alcohol (CTS/PVA) membrane demonstrated superior sensitivity in detecting pH variations in the surrounding environment, confirmed by a higher correlation coefficient (R2) between the generated TVB-N and the total color difference values (ΔE) than those of the pristine CTS or PVA film.

Investigation of anti-ozone effects of phenolic natural antiozonants in cis-1,4-polybutadiene rubber composites via molecular simulation and experimental validation

This article utilizes molecular simulation and experimental validation to conclude that the anti-ozone effects of three natural antiozonants are pterostilbene > flavonols > ferulic acid. In particular, molecular simulations analyzed the effects of chemical and physical factors on the effectiveness of the antiozonants, and found that physical factors had a greater influence if comparing with chemical factors in these systems.

Dual-active-layer flexible piezoresistive sensor based on wrinkled microstructures and electrospun fiber network for human-related motion sensing applications

A dual-active-layer flexible pressure sensor was developed by assembling a wrinkled microstructure of rGO film and a TPU/PDA/MWCNTs electrospun fiber membrane as the active layers on interdigital electrodes. The sensor enabled human motion monitoring, demonstrating its feasible applications in wearable electronics and human–machine interface devices.
