Contact Angle Goniometer with Video System

- Provide a quick evaluation for surface properties change
- Estimate surface energy of a solid (i.e. contact angle, sessile drop) or a liquid (i.e. pendant drop)
- Determine the interfacial energy between two liquids (i.e. pendant drop)
 

Inverted Microscope Video System with DIC, Phase Contact and Fluoroscent Attachments

(the video system is connected to the right, not shown here)

- Provide an quick examination of surface morphology at the microscopic level
- Capable of imaging in the bright-field/dark-field, polarized light, reflected and transmitted light, phase contract, differential interference contrast and fluorescent
  (to view selected images generated using this optical microscope)
 

Manual Ellipsometer

- Measure film thickness and refractive index of polymer films as well as SAMs
 

Portable Microscope Video System

- Provide the flexibility for examinating materials surface structures at various angles and locations
 

Scanning Probe Microscope (SPM) and its Video System

- Capable of contact mode, non-contact mode (AC), and pulse-force mode imaging
- Obtain the topographic information as well as lateral force, material stiffness at both micro and nano scales
  (to view selected images generated using this SPM)
 

Self-assembled Monolayers (SAMs) Deposition System

-  Achieve pressure from 1 atm down to 10-3 torr
-  Generate well organized Self-assembled monolayers (SAMs) for most organosilanes
-  No solvent is required, thus eliminating the interactions between substrate and solvent
 

Thin Film Generation System

-  Generate polymer thin films with thickness ranging from a few nanometer to several microns
 

Cleaning Equipments:

UV-Ozone cleaner

-  Remove organic contaminations or organic thin films
-  Generate a thin oxide layer on the substrate

Soxhlet Extractor and Ultrasonicator with temperature controls

-  Remove loosely attached chemicals
