Industrial Polymer Physics, Chemical Researcher and Lithium Ion Battery Expert

Technical Consultant #2509



Over forty years industrial experience with emphasis on new products development and customer service work in Li ion battery, electronics materials, adhesives and carbon fiber composites. Specialized in polymer physics, colloid science, characterization and fundamental research work for various applications, such as in electronics, constructions, carbon fiber composites, Li ion Battery, coatings and adhesives. 

  • Li ion Battery (raw materials).
  • Carbon fiber and its composites and prepreg.
  • Construction materials (Concrete superplasticizers, MHEC, RDP)
  • Water soluble polymers (Cellulose ethers, MC, HEC,CMC,EC,HPC from Ashland/Hercules),and applications.
  • Polyvinyl Pyrrolidone (PVP), SMA and Gantrez (from Ashalnd/ISP) and applications.
  • Tackifier resins for adhesive and sealants (Hydrocarbons and Rosin esters from Eastman Chemicals). Production and applications.
  • Rheology of Pressure sensitive adhesive formulations (thermoset, thermoplastics and UV).
  • Cationic polymers for personal care applications (conditioner and shampoo).
  • Acrylate Chemistry for rheology modifier, dispersants and hydrogels (Carbopol).

 Proven Success Programs

  • Developed and patented new binders for Silicon Carbon anode for Li ion battery application.
  • Developed and patented new binders for ceramic coated separator for Li ion battery application.
  • Set up joint develop programs with major Li ion battery producers in Asia and USA.    
  • Developed construction material (redispersable powder, RDP) for tile cement and had built new RDP plant in Nanjing, China, ($800 million market potential).
  • Developed rheology modifier for personal care (Carbopol) and qualified it at L'Oreal.
  • Development of new polymers for conductive pastes for solar cell.
  • Developed new pigments dispersants based on acrylate chemistry for $50 million, (Market potential in concrete admixture and water treatment applications).
  • Developed new photo-imageable solder mask formulations and liquid photo resist based on new acrylic chemistry (Business was sold to McDermid Inc.)
  • Developed and patented damage tolerant carbon fiber composite products qualified by Boeing 777 as the first in the world. Product was commercialized in 1988 and sold, exceeding $100 million, holding at present in the aerospace industry. This business was sold to Hexcel.
  • Developed new high temperature flex circuit adhesive based on polyimide.
  • Developed hot melt pressure sensitive adhesives for diaper applications for P&G and sold it more than $10 million (this resin business was sold to Eastman Chemicals).
