RESEARCH EXPERIENCE
Research Assistant, DoctoralResearch, Advisor: Rudolf Faust 2012-2016
Project: Synthesis, characterization and properties ofmodel thermoplastics polyurethanes(TPUs)
 Synthesized polyisobutylene (PIB) diol using living cationic polymerization following with
hydroboration/oxidation and characterized PIB diol using GPC, 1
H-NMR and HPLC.
 Synthesized amine terminated monodisperse hard segments containing two to four 4, 4’-Methylene
diphenyl diisocyanate units extended by 1, 4-butanediol and characterized them using 1
H,13
C-NMR.
 Prepared TPUs using PIB or PTMO diol with monodisperse hard segments and studied their thermal,
morphology (AFM and SAXS) and tensile properties.
Co-projects:
 Prepared monolayer poly (2-methacryloyloxyethyl phosphorylcholine) (PMPC) on gold using ATRP.
 Studied the self-healing properties of coumarin functionalized PIB based network.
 Assisted in the preparation of highly reactive polyisobutylene (PIB exo-olefin).
Research Assistant, Advisor: Prof. Lianshi Wang SCUT, Guangzhou, China 2009-2011
Project: Formulation of waterborne polyacrylates coating using solution/ emulsion polymerization
 Esterification of acrylic acid with pentaerythritol or Boltorn H20 and copolymerized it with other
acrylics monomers.
 Formulated and sprayed waterborne polyacrylates based automobile coating with functional additives
and tested the physical properties according to the standards.
 Mentored two undergraduates to win the excellent thesis.
Research Assistant,Advisor: Prof. Wei Yang SCU, Chengdu, China 2007-2008

2.  Simulated the effect of the branch size of LLDPE on rheology properties using Metlab/Mathematics 3.
 Extensive study in polymer processing principle and structure-properties relationship of polymer
blends and composites.
