Method of synthesizing a thermally conductive and stretchable polymer composite
A method for synthesizing a thermally conductive and stretchable elastomer composite comprises mixing liquid metal and soft material (e.g., elastomer) in a centrifugal or industrial shear mixer under conditions such that the liquid metal forms microscale liquid metal droplets that are dispersed in the soft elastomer. Liquid metal-embedded elastomers, or “LMEEs,” formed in this manner dramatically increase the fracture energy of soft materials up to 50 times over an unfilled polymer. This extreme toughening is achieved by means of (i) increasing energy dissipation, (ii) adaptive crack movement, and (iii) effective elimination of the crack tip. Such properties arise from the deformability and dynamic rearrangement of the LM inclusions during loading, providing a new mechanism to not only prevent crack initiation, but also resist the propagation of existing tears for ultra-tough, highly functional soft materials.

Smart Anti-Explosive Material
The invention relates to a material with high anti-explosivity and vaporization reduction, which is an alloy of aluminum, nano activated carbon or nano graphene and a plurality of other metal elements in the form of an engineered mesh (cylindrical forms—inner jacket) that represents 2% of the internal volume of the content of oil, its derivatives and gas. The material has high absorptivity and high absorptivity, suppresses the movement of gas particles and fumes, improves the flash point by 35%, the ignition temperature by 40% and reduces evaporation by 70%, thereby preventing the explosion of oil, its derivatives and gas upon exposure (fire, collision, static electricity, high heat, being struck by a projectile). Separately, the polymer sodium polyacrylate is added to crude oil to improve its properties and protect it from explosion.
