“…The mass ratio of PA 66 and PPO is fixed at 85:15. In order to improve the compatibility between PA 66 and PPO, the MA was chosen as compatibilizer, which was added during the extrusion process 31 . The weight of MA was 2 % of the PPO weight content.…”

A melting phosphorous‐nitrogen flame retardant was synthesized via the addition reaction of 9,10‐dihydro‐9‐oxa‐10‐phosphaphenanthrene‐10‐oxide (DOPO) and 2,4,6‐triallyloxy‐1,3,5‐triazine (TAC). The synthesized product from DOPO and TAC (DT) flame retardant possesses high thermal stability with T5wt% at 340°C, which can meet the high‐temperature processing for polyamide 6,6 (PA66) and other engineering plastics. The chemical structures of DT were characterized by nuclear magnetic resonance and infrared spectrometry. The PA composites were fabricated via blending PA66 with DT and poly‐phenyl ether (PPO) as charring agent. The results show that the PA composites exhibit strong flame retardancy with limited oxygen index reaching to 29.0%. As compared to the neat PA66, the total heat release and the effective heat of combustion were decreased by 27% and 21%, respectively. The mechanism study revealed that the thermal cleavage of DT gave the phosphorus‐containing free radicals and incombustible nitrogen‐containing gas, indicating the ability of DT to flame‐inhibition in the gas phase. Moreover, the char formation of the PA66‐based composites was facilitated by the synergistic effect from DT and PPO. This study may gain a potential technical route to manufacture the flame‐retardant PA66 materials for the melt spinning of fibers.

“…On the basis of thermoplastic PPO, various PPO alloys with PS [70,71], PA [72], PPS [73], EPDM [74], etc, have been also well investigated to modify their processability and mechanical strength, which have been commercially applied to the automotive industry, medical instruments, electrical and electronic products. In recent years, with the ever-growing demand for high-speed and high-frequency circuit boards, more and more modified low-molecular-weight PPO for thermoset laminate applications are synthesized to make up for the natural defects of the thermoplastic PPO itself, especially the processibility, poor dimension stability and organic solvent resistance.…”

With the rapid development of electronic information technology in the 5G era towards high integration, short propagation delay, and elevated assembly temperatures, more academic and industrial attention has been focused on high-frequency and high-speed copper-clad laminates (CCLs). Compared with conventional polymeric matrices, thermoset polyphenylene oxide (PPO) has become one of the most attractive resins applied in high-performance CCLs (HPCCLs) because of its excellent comprehensive properties, including outstanding dielectric properties, high thermal stability, great processibility, and low moisture absorption, etc. This review focuses on the history of the development of PPO prepolymers/oligomers, PPO-based thermoset resin systems, and PPO/inorganic filler composites to optimize the dielectric constant, dielectric loss, thermal conductivity, coefficient of thermal expansion, and mechanical properties. Moreover, some current challenges of PPO-based thermoset systems have been identified, such as developing feasible solutions to ensure the anti-aging properties for long-term reliability under harsh environments of high temperature, high humidity, and even high-frequency electromagnetic radiation. In general, more in-depth investigations of PPO-based thermoset systems for HPCCLs are required in the future.

Nylon is a human‐made material and has been applied in many industrial fields. This literature review explores the use of nylon in biomedical applications and discusses the properties and three‐dimensional (3D) printability of this material. Nylon is studied due to its versatility as an engineering plastic that can be easily transformed into fibers, films, and molded parts. Due to nylon's biocompatible nature, it has desirable chemical stability and tunable mechanical properties making this material and its derivatives widely used as sutures, catheters, dentures, and so on. However, the interactions between nylon and human body tissues have yet to be fully understood. Nevertheless, nylon is hybridized with different materials and used as skin dressings. In recent years, nylon composites have been actively researched in tissue engineering as an alternative to metallic implants with an appropriate bioactivity potential for bone growth. As nylon is supposed to be in contact with the tissue for a long time, hence researchers are developing antimicrobial strategies for the nylon materials to even promote their potential a step further. The 3D printing of nylon is currently confined to specific applications due to the printing technology's current limitations.
