Summary: Starch with active hydroxyl groups has become a popular choice for gel preparation in recent years. However, current starch-based gels often have unsatisfactory mechanical properties, self-healing properties, self-adhesion properties, and low-temperature resistance. In this study, a multiple network structure of amylopectin-carboxymethyl cellulose-polyacrylamide (ACP) gel was prepared, and tannic acid (TA) was used to enhance its performance. The ACP gel demonstrated high elongation at break, strength, self-healing performance, self-adhesion behavior, extraordinary low-temperature resistance, and self-extinguishing ability. It also showed potential in various applications such as sensor devices and temperature monitoring.

Summary: UV-curable coatings are gaining more attention for their high performance and environmentally friendly advantages, meeting coating development requirements. Vinyl oligomers play a key role in coating performance but face challenges due to high viscosity and low vinyl functionality. By polymerizing acid anhydride and glycidyl methacrylate, polyesters with lateral double bonds were prepared, with epoxy compounds used to adjust resin viscosity and functionality. Characterization of the polyesters' molecular structure and weight showed that specific acid anhydrides and glycidyl ethers significantly affected coating film properties, with specific ratios resulting in low viscosity and high hardness paint films with excellent water and alcohol resistance.

Summary: In this study, a DOPO-anchored benzothiadiazole flame retardant (DOPO-BTD) was successfully designed and synthesized for flame-retarded epoxy thermosets. The incorporation of DOPO-BTD significantly improved the flame retardancy and thermal stability of the epoxy matrix. The results showed a significant reduction in peak heat release rate (PHRR), total heat release (THR), smoke production rate (SPR), total smoke production (TSP), and carbon monoxide production (COP) with the addition of DOPO-BTD. Furthermore, the flame-retarded mechanism of DOPO-BTD was confirmed through gas-phase and condensed-phase pathways. This study highlights the potential of P/N/S synergistic flame-retardants for the development of functional polymers.

Summary: In order to address the issues of film smoothness and flammability in aqueous polyurethane dispersions (PUD), two hydrophilic chain extenders were used to regulate particle size and a flame retardant was added to prepare a self-matting and flame retardant PUD. The structure of the latex films was characterized using various techniques, and the results showed that adjusting the R-value and soft segment content affected the viscosity and glossiness of the film. Increasing DMPA content initially reduced glossiness, while increasing A95:molar ratio affected glossiness. The addition of FRC-6 improved flame retardancy and reduced glossiness, resulting in a PUD with a glossiness of 6.0% and flame retardancy rating of level 4.

Summary: Two new photoinitiators, NHPO and BHPO, containing triphenylamine and pyrene group, were designed and synthesized. NHPO showed a higher solubility (13.7 wt%) in TMPTA compared to TPO (12.5 wt%). UV-Vis spectra indicated that NHPO and BHPO had redshifted maximum absorption wavelengths at 397 nm and 419 nm, with molar extinction coefficients of 19,057 and 24,257 M-1 cm(-1), respectively. Real-time Fourier transform infrared spectroscopies revealed that NHPO achieved a higher degree of double bond conversion (65%) compared to TPO (45%), demonstrating superior photoinitiated properties. Photocuring mechanism studies showed that NHPO and BHPO generated two free radicals. NHPO exhibited excellent biocompatibility and low migration rate of 0.23%, making it a potential candidate for food packaging coatings.
