Abstract
This invention generally relates to a method for modulating interfacial wettability of a noncovalent nanoscopic monolayer or thin film. Particularly, this invention relates to a method for modulating interfacial wettability of a two-dimensional (2D) material using a molecular layer prepared from a polymerizable amphiphilic monomer having a hydrophilic head and a hydrophobic tail, wherein enhanced or decreased wettability of said 2D material is achieved by proper allocating the position of polymerizable group relative to the hydrophilic head and the hydrophobic tail.
Claims19
A method for modulating interfacial wettability of a two-dimensional (2D) material using a molecular layer prepared from a polymerizable amphiphilic monomer having a hydrophilic head and a hydrophobic tail, the method comprising the steps of
- a. preparing an amphiphilic monomer, allocating a proper position for the polymerizable group, relative to the hydrophilic head and the hydrophobic tail of said amphiphilic monomer;
- b. assembling a monolayer or thin film of said amphiphilic monomer;
- and
- c. polymerizing said amphiphilic monomer whereby affording said 2D material with a nanoscale enhanced or decreased wettability controlled by said amphiphilic monomer.
A method for modulating interfacial wettability of a 2D material using a molecular film prepared from a vicinal diyne amphiphilic monomer having a hydrophilic head and a hydrophobic tail, wherein said hydrophilic head is a carboxylic acid, the method comprising the steps of
- a. preparing a vicinal diyne amphiphilic monomer having a hydrophilic head and a hydrophobic tail;
- b. assembling a monolayer or thin film of said amphiphilic monomer;
- c. polymerizing said monolayer or thin film whereby affording a 2D material with enhanced or decreased wettability;
- and
- d. adjusting pH of said amphiphilic monolayer and/or chelating said carboxylic acid functionality with a divalent cation to further control head group ordering.
