    Abstract

    The objective of the present study is to investigate the effect of electrospun nanofiber reinforcement on the properties of commercially available, hyperbranched polymer modified (Hybrane, 0.3wt.% DSM) dental formulations. The emergence of functionalized nanoscale reinforcements having large surface area (hundreds of square meters/gram) has enabled the design of novel nanocomposites with new and complex structures leading to enhanced mechanical and physical properties. Electrospun nanofibers from a range of polymer chemistries (PVOH, PLLA, Nylon 6) have been investigated as a reinforcing phase at levels between 0.01 and 0.3wt.%, with and without a silane coupling agent surface treatment. The experimental results indicate that 0.05wt.% reinforcement with 250nm diameter PVOH nanofibers leads to a 30% improvement in compressive strength, coupled with a shrinkage reduction of about 50%. Electrospun fiber reinforcement by other chemistries or at other diameters showed either no property improvement or led to property loss.
