An alternative procedure for synthesizing 2,4,6-tris(2,2,2-trinitroethylamino)-1,3,5-triazine was developed. Nitration of this compound gave hitherto unknown 2,4,6-tris(2,2,2-trinitroethylnitramino)-1,3,5-triazine, which is of interest as potential component of solid rocket fuel compositions.

Heat transfer performance remains a key factor for the potential application of microencapsulated phase change materials (microPCMs). The purpose of this work is to explore the effect of different amounts of graphene added on the thermophysical properties of microPCMs. Microcapsules containing n-hexadecane (C16) with a melamine-urea-formaldehyde (MUF) shell were synthesized by emulsion polymerization. The spectra of Fourier transform infrared spectroscopy (FTIR) confirmed that the MUF shell is fabricated on the surface of C16. Graphene is successfully mixed with microPCMs and the crystal type of microPCMs is not changed, which is detected by X-ray Diffraction (XRD). The results indicated that heat enthalpy of microPCMs gradually decreases with the rising addition of graphene, but the heat transfer performance and thermal stabilities are enhanced. In addition, graphene in microPCMs obviously reduces the degree of supercooling of C16. MicroPCMs with 0.05 wt% added graphene have the best anti-osmosis performance.

In recent years, soy protein adhesive, as an environmentally friendly bio-based adhesive, has attracted extensive attention. In this study, in order to ameliorate the bonding quality of soy protein isolate (SPI) adhesive, the melamine-urea-formaldehyde prepolymer (MUFP) was synthesized, and different amounts of it were introduced into the SPI adhesive as a cross-linking agent. Fourier transform infrared (FT-IR) spectroscopy, gel permeation chromatography (GPC), thermogravimetric analyze (TGA), and scanning electron microscopy (SEM) were used to analysis the mechanism of modification. The results of plywood test indicated that the wet bonding strength of the adhesives was first increased and then decreased with an increase in the amount of MUFP additive. FT-IR, TGA, and SEM tests suggested that the introduction of MUFP could promote the establishment of a cross-linking structure in the cured adhesive layer to improve the bonding quality of adhesives, but presence of excessive MUFP could introduce hydrophilic groups and adversely affect water resistance.
