英文摘要: The present work will proceed a thorough investigation on the mechanical behavior of POSS hybrid nanocomposites by the ways of theoretical analysis,MD simulation and experimental examination. Attention is focused on the influnce of POSS hybrid process on the elastic modulus,hardness,toughness and volume shrinkage of the crosslinked polymer networks. A mechanics model for POSS hybrid reinforcement should be proposed. Based on it, A prediction may be given on the mechanical properties of the POSS hybrid nanocomposites. These works may lay the foundation for further molecular design of the improved dental restoratives.
