Summary: Although flame retardant polymers with low heat release have been developed, suppressing smoke remains a challenge. This study focuses on adjusting key intermediate-polycyclic aromatic hydrocarbons (PAHs) during burning processes to reduce smoke release. By chemically modifying ammonium polyphosphate (APP) with a benzimidazole structure, the trinity flame retardant (APP-BIM) was obtained. The research model, unsaturated polyester resin (UP), exhibited excellent thermal stability and fire safety. Additionally, a homemade smoke sampling module (SSM) coupled with a cone calorimeter (Cone-SSM) was developed for in-depth investigation of smoke suppression mechanism. This strategy offers a promising approach to decrease the fire hazard of polymers.

Summary: A fully biomass intumescent flame retardant (IFR) system was developed by blending a reaction product (PA@HS) of phytic acid (PA) and hydrolyzed silk (HS) with potato starch (PS), and then combining it with polyacrylonitrile (PAN) to obtain flame retardant PAN (FR-PAN). The resulting FR-PAN showed improved tensile strength, elongation at break, and reduced heat release rate and smoke production rate, indicating excellent flame retardant and smoke suppression performance. Furthermore, the waste FR-PAN materials were successfully recycled through the preparation of FR-PAN Char (FRPC) for cellulose and polyvinyl alcohol (PVA) modification, leading to enhanced fire safety.

Summary: This study focuses on manganese doped CdS thin films synthesized by chemical bath deposition. The incorporation of Mn2+ cations in CdS was found to influence the crystalline structure, morphology, and optoelectronic properties. Doped thin films exhibited a uniform hexagonal structure, changed growth orientation, and showed scale-like and needle-like morphologies. The bandgap and rectification speed of Schottky diodes were modified by introducing manganese. This study suggests the potential for affordable high-speed optoelectronic devices.
