Film Morphology and Film-Forming Ability of Supramolecular Compound Self-Assembled with Amino Polysiloxane Emulsion and Carboxyl Polysiloxane Emulsion

Abstract:

Using cation amino polysiloxane emulsion(ASE) and anion carboxyl polysiloxane emulsion (CSE) as materials, mixing ASE and CSE together to self-assemble or aggregate by electrostatic interaction, supramolecular compound emulsion (ASE-CSE) was formed. TEM and particle size analyzer observation showed that the particle of ASE-CSE is sphericity, and its particle diameter is bigger than that of mono-composition emulsion and has single-peak distribution. SEM, atomic force microscope (AFM) and other instruments detections indicated that the ASE-CSE possesses good form-film property. The ASE-CSE film on the silicon wafer is very rough. There are many islands or peaks package on the film surface. The average thickness of the film is 12.45nm, and it is about 7.1 times as against ASE. With the ASE-CSE film, the stripes or grooves on the fiber surface is weakened or disappeared. And the surface is smoother than that of the control sample. In addition, the contact angle of the cotton fabric treated by ASE-CSE is 86.5°. This reveals that the ASE-CSE film brings fiber fabric from hydrophile to hydrophobe.
