Partial Results From Summer

I haven’t posted my summary blog of this past summer until now because I have been communicating with my professor and other members of the research group, as I tried to make sure the results that I am about to publish are ready for public. I know when I posted my first blog, I talked about the topic of my research, which was Interfacial Characterization of Graphene/Polyamide Nanocomposites. It focused on understanding the interaction of graphene oxide (GO) and polyamide (PA) as materials for nanocomposites. I mentioned that the fundamental features of the interface could be very significant for future research on optimal selection of materials, as well as incorporation, for graphene/polymer nanocomposites.

Hydrophobe and Hydrophile

Hydrophobicity is the property that a molecule repels from the contact with water. You can always see leaves or grass with dews on them – if the leave or grass is hydrophobic, the dew would tend to look like a perfect sphere. And the dew rolls down easily when you gently shake the leave. A hydrophile, on the contrary, likes interacting with water molecules. A water drop on a hydrophilic surface has the contact angle smaller than 90 degrees.
