Stability petroleum matrix

The stability of organometallic or inorganic compounds in a petroleum matrix is an important consideration in the sampling process. Stability studies on selected organometallic standards in petroleum... 

Vulcanized rubber compounds are usually reinforced by inorganic filler and/or carbon black to improve the mechanical properties, the thermal stability and the gas barrier properties of the bulky polymer. Carbon black is the most suitable reinforcing agent in the rubber industry thanks to the strong interaction with the polymer matrix. However, due to its polluting nature, the ubiquitous black color of the compounded material and its dependence on petroleum stock pushed the academic and industrially research to look out for other so-called white filler. In this sense, clays seem to be a good choice to replace conventional filler increasing the bulky PB performances. 

Cellulose has been identified as a source of biopolymer that can be used as a substitute for petroleum polymers. EPN have been successfully synthesized from cellulose acetate, triethyl citrate plasticizer, and organically modified clay (Misra 2004). The polymer matrix for nanocomposite contains 80 wt% pure cellulose acetate and 20 wt% triethyl citrate plasticizer. Results show that better exfoliated and intercalated structure were obtained from nanocomposites containing 5 and 10 wt% organoclay compared with that of 15 wt% organoclay. Tensile strength of ceUulosic plastic reinforced with 10 wt% organoclay improved by 180 % and thermal stability of the cellulosic plastic also increased. 

The polymer matrix is the scaffolds for the conductive filler networks, their chemical, and physical properties can affect the electrical performance of the s-CPCs. Polyethylene (PE) is a commonly used petroleum-based material with good chemical stability, which can bear acid- and oxidation corrosion. With the...
