International Human Development Indicators - UNDP


International Human Development Indicators

The human development data utilized in the preparation of the Human Development Index (HDI) and other composite indices featured in the Human Development Report are provided by a variety of public international sources and represent the best and most current statistics available for those indicators at the time of the preparation of this annual report. Calculations of HDI values and country rankings are the sole responsibility of the Human Development Report Office. The 2011 Human Development Report, an editorially independent publication commissioned by the United Nations Development Programme, was published in print and on line on November 2nd, 2011. Read more

IYC 2011 - Polymer International

Table of Contents for Polymer International

Keywords:

  • nanocomposites;
  • surface functionalization;
  • silica;
  • zirconia;
  • mechanical properties

Abstract

Epoxy resin nanocomposites were prepared by curing bisphenol-F with an aliphatic amine in the presence of SiO2 and ZrO2 nanoparticles as inorganic fillers. Both types of particles were prepared with diameters of around 10 nm and 70 nm to study size effects in the nanocomposites. The nanoparticles showed a different constitution: while silica was amorphous and spherical in nature, zirconia was crystalline and non-spherical. Both nanoparticles were surface-functionalized with novel diethylene-glycol-based capping agents to increase the compatibility with the epoxy matrix. The organic functionalities were attached to the nanoparticle surface via phosphonic acid (zirconia) and trialkoxysilane (silica) anchor groups. The homogeneity of the distribution of surface-modified inorganic nano-sized fillers in the matrix up to 5.8 vol% in case of silica and 2.34 vol% in case of zirconia was determined by small-angle X-ray scattering and transmission electron microscopy. Mechanical properties such as hardness and storage modulus were increased with increasing filler content while thermal stability of the obtained materials was nearly unaffected after incorporation of nanoparticles.
