Polymeric Nanocomposites Enabled by Controlled Architecture Materials
Shefelbine T.A., Marx R.E., Nelson J.M., Longabach J.W., Brostrom M.L., Bucket M.I., 3M Corporate Research, US
This presentation will focus on the use of Controlled Architecture Materials (CAMs): block copolymers, telechelic, gradient and star branched polymers as additives to induce the exfoliation of nanoclays in thermoplastic resins. Conventional exfoliation methods include [...]
Effect of Nanoclay Content on Mechanical Behaviour of TGDDM Epoxy Nanocomposites
Exfoliated nanocomposites based on tetraglycidyldiamino diphenylmethane (TGDDM) cured by diethyltoluene diamine (DETDA) reinforced with 1-20 phr of a commercial nanoclay (I30E) were prepared. The effect of the nanoclay content on the compressive modulus of the [...]
The Impact of Nano-Materials on Coating Technologies
Nanocomposite coatings are made by embedding nanocrystalline metal oxide particles in a polymer matrix. The benefits accrued by incorporating nanoparticles into a polymer matrix become economically driven when several advantageous properties are obtained simultaneously, compared [...]
