摘要:
A method of preparing a cured thermoplastic material includes curing a thermoplastic polymer having a thermal decomposition temperature greater than or equal to about 200° C., at a temperature of about 200° C. to about 400° C., for a total time of less than or equal to 200 hours. A method of making a shape memory material also includes curing a thermoplastic polymer to prepare a cured thermoplastic material.
摘要:
A thermoplastic material comprises the cure product of a thermoplastic polymer having a thermal decomposition temperature greater than or equal to about 200° C., the thermoplastic polymer being cured at a temperature of about 200° C. to about 400° C., for a total time of less than or equal to 200 hours. An article is formed from the thermoplastic material.

摘要:
Methods of making elastomeric nanocomposites with improved nanoparticle dispersion in the elastomer are described. The method includes the use of liquid form additives such as oils, plasticizers and/or solvents as dispersing agents to disperse nanoparticles into elastomers. Also described are articles such as downhole elements including the elastomeric nanocomposites made by the methods described herein.
摘要:
An actuator including an actuation member at least partially defining a chamber and a fluid generating media disposed in the chamber. The fluid generating media includes a first electrochemical composition and a second electrochemical composition. The first and second electrochemical compositions are together electrochemically responsive to a first fluid for generating a second fluid. The actuation member is actuatable via a pressure of the second fluid. A method of controlling an actuator is also included.
