The structure,synthesis,sythetic mechanism,protonation,application of polyaniline and the research advancement of polyaniline composites were comprehensively elaborated, and the study on coal based polyaniline was introduced in detail.In contrast with polyaniline,coal based polyaniline's conductivity drops slightly,but it has cheaper cost and strenghened thermal stability. The novel methods and the new chances for coal's nonfuel application are provided by coal based polyaniline.The coal based polyaniline has a certain extending value.

The thermal property of PHB and its modification was analyzed by TG/DTA.The rheology property of PHB was researched.The effect of talcum powder,calcium carbonate,DOP on the rheology property of PHB were investigated.The result showed that the viscosity of PHB declined rapidly with the increasing of shear rate.The addition of DOP could depress the melting point of PHB and slow the phenomena of shear thinning of PHB dramatically.Talcum powder could slow the phenomena of their shear thinning slightly.

This paper introduced the structure of polyaniline,and three methods for synthesis of water-soluble polyaniline.And the paper summarized the research advances of polyaniline in the field of anticorrosion coatings,and it expatiated the anticorrosive mechanism of polyaniline and application of polyaniline anticorrosive coat.We had expected foreground about polyaniline,and we think that the synthesis of water-soluble polyaniline and the analysis of corrosion theory need to be further studied.

ABSTRACT Liquid foods are classified and their properties discussed under various types of rheological behavior: Newtonian, pseudoplastic, shear thickening, thixotropic, and viscoelastic. Rheological data on selected liquid foods are summarized in either tabular form or in the form of equations. Wherever possible the influence of temperature, constituents, and structure on the rheological behavior is detailed. Because many foods are suspensions, the measurement of flow properties of suspensions and factors influencing their rheological behavior are also covered. Finally, the relationship between the flow behavior and the sensory evaluation of mouth feel and viscosity is discussed.

The influence of K+and Na+concentrations on the stability and rheological property of silica sol system have been studied by rheological method.The results show that the influences of K+ on the stability of silica sol is much larger than that of Na+.Under the low shearing rate,all discussing systems showed the typical disperse system of rheological properties,which is shear thinning.While under the high shearing rate,the resemble Newtonian fluid characteristics has been found.

OBJECTIVE:To evaluate rheological property of Qinyu burns gel by using dynamic rheology,and to evaluate gelling properties. METHODS:Rheological parameters were determined by shear rate and frequency scanning;viscoelasticity was determined by creep experiment. The stability of the gel was evaluated by stimulant modes of storage,transportation and application.RESULTS:Qinyu burns gel was shear-thinning pseudoplastic fluid. Its elasticity,viscidity and stability were satisfactory. CONCLUSIONS:The dynamic rheological experiments can characterize the gelling properties of Qinyu burns gel and provide basis for evaluation in vitro and quality control of products.

Abstract The melt rheological behavior of chloro‐polyether and polyepichlorohydrin blends was studied. It was found that both the coupled and uncoupled blends at different blending ratios are pseudoplastic, but there was a great difference in pseudoplastic behavior between them. All the blends obeyed the principles of temperature superposition and composition superposition for plots of shear stress vs. shear rate. A model is proposed to describe and predict the rheological behavior of the blends.
