Project: Water-borne Silylated Polyurethane Emulsions
for Water-borne Adhesives
-- Synthesized novel silylated polyurethane via batch
polymerization and prepared stable emulsions for adhesive
by means of phase inversion.
-- Designed and certified complex emulsifier system in
emulsion to protect silyl groups from reacting with water
-- Investigated viscosity, particle size, storage stability,
mechanical stability and freeze-thaw durability of emulsions.
Studied adhesive force, solvent resistances, stiffness,
mechanical properties and thermodynamic properties of
Part-time Research Assistant, Tsinghua University,
Project: Functional Polymeric Micro-spheres with
-- Prepared a series of latex micro-spheres via semi-continuous
emulsion copolymerization of styrene and sodium styrene
-- Studied the average diameter, polydispersity, morphology
and heat endurance of latex micro-spheres, as well as
the effects of the recipe and polymerizing route on them.

Project: Composite Polyurethane-Acrylate (PUA) Emulsions
-- Synthesized and characterized acrylate with urethane
segment and polymerized it with other unsaturated monomers
via emulsion copolymerization.
-- Synthesized pre-polymer of polyurethane and dispersed
it in butyl acrylate. Polymerized the butyl acrylate by
virtue of in-situ emulsion polymerization.
-- Investigated the particle potential, storage stability,
freeze-thaw durability and minimum film-forming temperature
of emulsions as well as the adhesive force, stiffness,
solvents resistances and thermodynamic properties of plated
