NANOPLAST - Nano-technological materials and products in the plastics industry

We have just started a new 3-year project, NANOPLAST, that runs from ultimo 2007 to ultimo 2010. The aim is to investigate physical, chemical, and toxicological properties of nano-technological materials that will obtain massive use in the future production of plastic products. The project focuses on polymer nano composites (PNCs) that consist of a polymer matrix containing a uniformly dispersed nano-technological material that can be nanoclay, carbon nanofibres (CNFs), or carbon nanotubes (CNTs). The starting point is to investigate 9 PNCs that are composed from 7 different nano-technological materials (nanoclay, CNFs, CNT) and 3 different polymers.

The main project will organize the obtained knowledge across three subprojects and carry through a comprehensive dissemination in collaboration with The Danish Plastics Federation, The Central Organization of Industrial Employees in Denmark, The Danish Working Environment Authority, and other relevant parties. The three subprojects are:

Subproject 1.: Characterisation of toxicologically relevant physical and chemical properties of nanoclay, carbon nanotubes and carbon nanofibres in pure state and of wear test dust from polymer nano composites

Subproject 2. Characterization of toxicological properties of nano-technological materials for use in plastic products. Specifically carcinogenic effects of nanoclay, carbon nanotubes and carbon nanofibre in pure state and of wear test dust from polymer nano composites.

Subproject 3. Assessment of the risk of exposure to nano-technological materials in the plastics industry – Exposure scenarios carried out during test productions in the laboratory.

The first step of the project is to produce real PNCs where the properties of the nano-technological materials are transferred to the polymer matrix. The key technological challenge is to disperse uniformly the nano-technological material within the polymer matrix and prevent their agglomeration during subsequent processing. In their pristine form, the nano-technological materials exhibit an extreme affinity to each other and readily form aggregates. Thus, a uniform dispersion of the nano-technological materials in the polymer matrix is of fundamental importance to realize property improvements. The physical properties of the PNCs will be tested by different methods to confirm that real PNCs have been obtained. The next step is to produce PNCs, produce wear test dust from PNCs for physical, chemical, and toxicological investigation and conduct exposure scenarios during test productions.
