Recent Achievements of Self-Healing Graphene/Polymer Composites

Joseph F. Schevtchuk Follow. Polymer matrix composites PMCs utilize thermoset resins in large part because of their low starting molecular weights which allow for good reinforcement infiltration prior to curing. Formed networks owe much of their mechanical properties to covalent crosslinks tethering molecules within the matrix. Traditional covalent bonds are irreversible and thus damaged composites are either repaired or replaced. For the former, traditional repair techniques remain costly and time consuming.

Self-healing polymers and composites utilizing the Diels—Alder reaction have received considerable attention due to the intrinsic healing capability of this crosslink. However past research focused on chemistries that cleave at low temperatures, which places limitations on the polymer's use temperature. It is shown that the self-healing behavior can be obtained purely through the reformation of mechanically cleaved DA adducts since the cleaving temperature is beyond the decomposition temperature. The self-healing polymer reported here is obtained from liquid monomers allowing the polymerization of bulk polymer samples and its infusion into continuous fiber reinforced composites. It is shown that the polymer can yield thermally stable composites with mechanical properties comparable to those of other engineering polymers and structural composites.

Self-Healing Materials Systems: Overview of Major Approaches and Recent Developed Technologies

Polymers are widespread in different sectors, from packaging to construction. In this scenario among emerging polymers there are self-healing polymers that falls into the class of smart polymers [5]. It is considered that in these compounds could carry to4. These groups can form oxidative products or rearrange themselves to repair the leak. In the first case the damage is repaired by means of an external agent put inside the matrix.

Therriault, E. Haddad, W. Box , Montreal, Canada. The development of self-healing materials is now being considered for real engineering applications.

Однажды в компьютере случился сбой, причину которого никто не мог установить. После многочасовых поисков ее обнаружил младший лаборант. То была моль, севшая на одну из плат, в результате чего произошло короткое замыкание.

Поэтому я хочу узнать мнение специалиста. - Что ж, - сказал Джабба, - мне неприятно первым тебя разочаровать, но твои данные неверны. - Ты так думаешь. - Могу биться об заклад.  - Он откусил кусок пирога и заговорил с набитым ртом.

Я скорее предпочту умереть, чем жить в тени позора. А ждет его именно. Он скрыл информацию от директора, запустил вирус в самый защищенный компьютер страны, и, разумеется, ему придется за это дорого заплатить. Он исходил из самых патриотических соображений, но все пошло вкривь и вкось. Результатом стали смерть и предательство.

Глаза его расширились от ужаса. - Нет! - Он схватился за голову.  - Нет. Шестиэтажная ракета содрогалась.

Self-healing materials have attracted much attention because that they possess the ability to increase the lifetime of materials and reduce the total cost of systems during the process of long-term use; incorporation of functional material enlarges their applications.
