Abstract:

Funding for this project was used to purchase three research grade instruments a mini twin-screw extruder, a dynamic mechanical analyzer, and a benchtop powder x-ray diffractometer. The new equipment has been used to prepare materials for fire testing, to assess crystallinity of our composite materials, and to examine the effects of flame retardants on the viscoelastic properties of the composites. Results have indicated that the use of POSS-modified cellulose improves multiple properties of polylactic acid and has significant advantages over conventional intumescing flame retardant additives. Furthermore, the equipment has been used to assess the properties of similar materials prepared in other collaborative projects. The measurements have already resulted in one publication, and several other manuscripts are in preparation. Acknowledgement to the Air Force Office of Scientific Research, including the award number for this grant, has been included in these manuscripts.
