        摘要：The application and preparation methods of microcrystalline starch were reviewed in this paper. According to the primary procedure of the formation of microcrystalline starch, the preparation methods were classified as retrogradation, hydrolyzation and crystallization.On the basis of classification by the crystal type (A-, B-, C-and V-type), microcrystalline starch can be classified into retrograde, original and crystal microcrystalline starch by the difference of the preparation methods.The meaning of microcrystalline starch was defined in the article which was proposed that, microcrystalline starch is a kind of aggregate of microcrystal strand, crystalline lamellae or other crystal form with high crystallinity.The crystal type and the crystal type transform of microcrystalline starch were also described in detail.

        摘要：Polymer-based clay nanocomposites display rheological properties similar to those of normally particle-filled polymers.The formers’dynamic storage and loss moduli increase with increasing the content of clay at all frequencies and their frequency-dependence exhibits nonterminal behavior at lower frequencies or higher frequencies;further, the storage modulus shows a solidiike plateau at lower frequencies when the content of clay exceeds a critical value.However, the polymer-based clay nanocomposites exhibit nonterminal behavior or solidlike behavior at low content of clay(usually, <10%(wt)), while the normally particle-filled polymers display those behavior at high content of fillers(usually, >40%(wt)).In addition, these rheological features are also dependent upon the aspect ratio, chemistry of clay, structural parameters of polymer matrix and the strength of interactions between polymer matrix and clay.The rheological behavior of polymer-based clay nanocomposites is closely associated with the formation and evolution of their microstructure involved in materials as well as the viscoelastic relaxation processes of polymer chains under specific conditions. The rheological properties and specific viscoelastic relaxation mechanisms of intercalted, delaminated and end-tethered and exfoliated clay/polymer nanocomposites under the external force field were reviewed in this paper.
