A nanocomposite has components that occur on the macroscale.

• TRUE

• FALSE

How are hybrid materials different from other composite materials?

• The components of hybrid materials are blended together at the molecular level.

• Hybrid materials only have one component.

• The components of hybrid materials interact with each other only physically.

• What are you talking about? Hybrid materials and composite materials are literally the same????!!!!

Which of the following statements about hybrid materials is most true?

• Hybrid materials have only inorganic components interacting with each other.

• Hybrid materials have only organic components interacting with each other.

• Hybrid materials have both organic and inorganic components interacting with each other.

• Hybrid is just a fancy way of classifying a material I know nothing about.

Which of the following best describes hybrid materials?

• A special type of composite material with two or more components at the molecular or on the nanoscale blended together to create new and unique properties.

• A special type of composite material with only one component at the molecular or on the nanoscale blended together to create new and unique properties.

• A special type of composite material with two or more layers that has new and unique properties.

• A special type of composite material with two or more components at the molecular or on the nanoscale blended together to improve existing properties.

What is the best way to classify hybrid materials?

• According to bond strength.

• According to type of modification.

• Both are good.

• What is going on here? I'm confused.

Class I hybrid materials have strong chemical interactions.

• TRUE

• FALSE

Interpenetrating networks are formed when there is simultaneous crosslinking between the organic components and the inorganic components. Here, as the organic matrix is formed, the inorganic particles also form a network. These networks are intertwined.

• TRUE

• FALSE

All of the following are strong chemical interactions except...

• Ionic bonding.

• Coordinate bonding.

• Covalent bonding.

• Hydrogen bonding.

Which of the following is NOT an approach to in-situ hybridisation?

• Building block approach.

• Sol-gel method.

• Emulsion polymerisation.

• Blending.

Which of the following statements are true?

1. I. Hydrolytic sol-gel synthesis occurs in the presence of water.

2. II. In melt blending, organic and inorganic nanoparticles are mixed together in aqueous media.

3. III. During emulsion polymerisation, inorganic seeds are used to stabilise organic nanoparticles to form composite colloids.

• I and II

• I and III

• II and III

• I, II, and III
