“…Melamine-formaldehyde (MF) resin is a typical thermosetting amino resin extensively utilized in adhesives, coatings, fibers, foam plastics, leather tanning agents, decorative laminates, molding compounds, and other products, owing to its desirable features including excellent physicchemical stability, good weather resistance, satisfactory adhesion to various substrates, high hardness and stiffness, low flammability, good optical performance, and lowcost. [1][2][3] In addition, MF resin is widely applied to prepare foam products. For instance, the researchers have exploited MF to shell materials for microcapsules containing self-healing agents, flame retardant, electronic ink display technique, and phase change materials.…”

Melamine‐formaldehyde (MF) foam, while intrinsically flame retardant, necessitates further refinement to meet stringent fire safety standards, particularly in terms of heat release rate and thermal stability. In this study, an innovative approach was adopted wherein an inorganic substance, potassium water glass (WG), was employed to create an encapsulation layer on the surface of the MF foam structure via a straightforward dip‐coating technique. The composite foam underwent a comprehensive analysis of its structure and flame retardant characteristics, using test evaluations such as micro‐scale combustion calorimeter (MCC) testing, cone calorimeter testing (CCT), and thermogravimetric‐Fourier infrared spectrometer (TG‐IR) assessments. It was found that the even coating of WG on the MF foam surface profoundly enhanced the foam's structural integrity. Utilizing the shielding properties of this inorganic layer, the hybrid foam's thermal stability experiences a remarkable augmentation. The peak of heat release rate (pHRR) and the total heat release rate (THR) of the MF foam experienced an impressive reduction of 85.2% and 78.8%, correspondingly. Notably, this advancement is concomitant with a substantial decrease of 39.2% in the total smoke release (TSR) and a notable amelioration in mechanical characteristics. Such developments undeniably broaden their application horizons across diverse domains.

The low toughness and high softening temperature of bismaleimide (BMI) resin limit its application in the field of electronic packaging. Herein, a series of flexible BMI resins with maleic anhydride terminated were synthesized via the imide reaction between dianhydrides and bio‐based 8,8′‐(4‐hexyl‐6‐octylcyclohexane‐1,3‐diyl)bis(octane‐1‐amine) (HOBOA). The degree of polymerization of these BMI resins was controlled to 1, 3, and 5 by adjusting the molar ratio of dianhydrides to HOBOA. These BMI resins show a low softening temperature below 100°C. These BMI resins were cured by the thermal procedure as follows: 145°C/2 h, 185°C/2 h, 225°C/2 h, and 275°C/2 h. The thermal decomposition temperature of cured resins is above 395°C. The tensile testing results demonstrated that cured resins exhibit a high elongation at break of around 60%. The dielectric constant of the cured resins is between 2.72 and 3.09 at room temperature. The water absorption rate of cured resins is less than 0.7% after being soaked in water for 30 days. After the cured resins were soaked separately in acid and alkali, the tensile strength retention rate reaches more than 90%. Additionally, the lap shear strength of cured resins coated on 7075 aluminum alloy exceeds 7.0 MPa.
