Hybrid Polymers

Competitive advantages


Anti-microbial, anti-oxidant, conductive and gas permeable hybrid polymers are transformational technology.

They incorporate both commercial substrates and new age conducting polymers to provide a fast track for New Zealand companies into the new age of nanotechnology.

How might this technology give you a competitive edge?

Let's take milk as an example. It once had a one-day shelf-life. Pasteurisation increased that shelf-life to 3-5 days if refrigerated. High temperature pasteurisation increased that shelf-life to 2-3 weeks. Ultra high pasteurised milk can last 2-3 months. Ultra heat treatment (UHT) with sterile handling and container techniques may take that to 3-4 months.

Now, think about how our technology might work for apple juice in terms of mainaining quality and extending shelf-life.

The hybrid plastics we’re developing will offer competitive advantages because they are:


  • They have free radical scavenging (antioxidant) capacity and electrical conductivity.
  • They’re active at a low concentration against a wide range of bacteria, fungi and viruses, including MRSA.


  • They can be used powders, aqueous dispersions (nano-particles), coatings on a wide variety of substrates, or as dispersions in liquid or solid resins.
  • The technology can be applied in industries ranging from packaging to water quality, medical facilities, and hearing devices.
  • We can attach polymer technology to a large range of substrates – from biopolymers, elastomers, metals, oxides and zeolites. No other industrial anti-microbial agents have this level of compatibility.
  • Plastics now have a new multi-functionality not possible before.
  • Stable
  • They’re stable in air, so there are no special handling or storage conditions. They’re thermally stable up to 250-300oC, making them compatible with conventional thermoplastic melt processing. Other forms are insoluble in water, so there’s no risk of leaching.


  • They’re based on low cost industrial chemicals. The high efficacy means low loading and added value much greater than added cost.


  • They are non-cytotoxic against human fibroblasts and at concentrations lethal for bacteria.

….what’s coming

  • Anti-microbial electrospun fibres to promote the healing process.
  • Colloidal polymers with potential as spray-on technologies.
  • Coated or bonded to metals,oxides and molecular sieves (zeolites).
  • Surface layers on silicone films.

It comes down to this

Hybrid polymers are novel combinations of commercial polymers and conducting polymers which exhibit exceptional and commercially valuable properties - including anti-microbial, anti-oxidant and gas permeability control capabilities.

New Zealand has a small–country economy. Innovation, transformation and commercialisation may offer the best opportunity for maximising investment here and developing high-tech exports. A transformational product like hybrid polymers can:

  • Contribute directly to the development of new, high value industrial, food and hygiene applications.
  • Create new opportunities for innovative New Zealand companies with a flow-on to our economy.
  • Offer potential on the international market.
  • Boost our technological expertise and foster commercialism.
  • Help New Zealand companies will attract and retain highly-skilled staff.
  • Suggest new products, new skills and new markets.
