Developing silicones that are friendlier toward health and the environment

Polysiloxanes, the scientific name for silicones, possess exceptional properties, and are used in numerous fields ranging from cosmetics to aerospace. They are absolutely everywhere. However, they have a major flaw, as small, cyclic oligosolixanes—toxic for the environment and identified as an endocrine disruptor—form during their synthesis. To correct this drawback, a team of scientists led by a CNRS researcher recently developed a new process for synthesizing silicones in a cleaner and more environmentally-friendly manner by preventing the formation of these small cyclic oligosolixanes.

Tried to do a pewter cast of my dog's jawbone today :) I'm still a noob when it comes to mold making though so it's not perfect.. But fun anyway! :D

Give it the plasma treatment: Strong adhesion without adhesives

Polymers containing plastics are essential in modern life. Being lightweight, strong and unreactive, a vast range of technologies depend on them. However, most polymers do not adhere naturally to other materials, so they need adhesives or corrosive chemical treatments to be attached to other materials. This is a problem in areas like food and medicine, where contamination must be avoided at all costs.

A clean way to make industrial polymers adhesive is urgently needed. Now, a team at Osaka University has achieved just that. They have developed a suite of plasma treatments to allow vulcanized rubber and the plastic PTFE (polytetrafluoroethylene) to adhere to one another, or to other materials. The method activates the polymers' surface chemistry, as described in a study in Scientific Reports.

"If you spray PTFE with a plasma of helium at 200 degrees, it can adhere to unvulcanized rubber -- this is a technique we developed earlier in our lab," says study lead author Yuji Ohkubo. "But vulcanized rubber presents a greater challenge. In our latest study, we customized a new plasma treatment for vulcanized silicone rubber, making it adhere strongly to PTFE for the first time."

Silicones obtained at low temperatures with the help of air

Russian scientists have developed a new method for synthesizing para-carboxyplenylsiloxanes, a unique class of organosilicon compounds. The resulting compounds are promising for creating self-healing, electrically conductive, heat- and frost-resistant silicones.

Organosilicon compounds, especially materials based on silicones, are among the most in-demand products. The ability to withstand incredible thermal and mechanical stress makes it possible to use silicones for sealing and protecting many items in aircraft and rocket construction. The strength and durability of silicones lends them to applications in medicine, food industry, and in many other fields of human life.

Though many silicone materials have already been created and their fields of application have been found, scientists believe that their usability potential has not been fully realized. This is due to one of the central problems in the modern chemistry of silicones, namely, the synthesis of organosilicon products with a "polar" (-C(O)OH, -OH, -NH2, etc.) functional group in an organic substituent. Such a moiety allows the easy introduction of other substituents, and the ability to tune the compound to repel water or to form stable aqueous emulsions, and to impart other "super-capabilities" to a material. This opens quite unique prospects for subsequent modification of these compounds in order to synthesize new copolymers, self-healing and conductive materials, and compounds for the storage and delivery of drugs and fuels. Just a small modification of a compound would also allow one to solve the problem of low mechanical strength and incompatibility of silicones with polymers, such as polyesters and others.
