1. When introduced into the polymer matrix , remote actuation of shape transitions is possible. 2. A hydrogel is a porous crosslinked polymer matrix filled with water. 3. This used wood flour fibres in phenolic resin as the thermoset polymer matrix . 4. They are also used as the thermoset polymer matrix in pre-pregs. 5. This is achieved by dispersing the particles throughout the polymer matrix . 6. There is a possibility of building ordered arrays of nanoparticles in the polymer matrix . 7. Many commercially produced composites use a polymer matrix material often called a resin solution. 8. In this technology, moldable polymer matrix emits light when exposed to an electric current. 9. Graphene is often produced as a powder and as a dispersion in a polymer matrix . 10. This allows for increased hydrogen bonding between adjacent polymers, giving the chitin-polymer matrix increased strength.
