Introduction As electrolyte materials, poly(vinylidene fluoride) blended polystyrene sulfonated acid (PVDF-g-PSSA) membrane was widely applied to the direct methanol fuel cell and low temperature all-solid-state gas sensors because of its good proton-conductivity and low methanol permeation coefficient[1].
Experimental Materials The PVDF(white solid) kindly provided by Shanghai San Ai New Material Limited company, was dried for 24 h in a vacuum oven prior to use.

The materials have much higher strength such as fast construction, high load bearing capacity, high construction quality but those have a fatal weakness as well.
The engineering method not only adopts a science but also an engineering experience.
The first one requires detailed information on the materials and processes such as mechanical, thermal databased at high temperatue of each structural steels and derivation of load-bearing capacity as the temperature within a fire compartmentation is going up.

Effect of Nano-scale TiN on the Mechanical Properties and Microstructure of Si3N4 Based Ceramic Tool Materials B.
Moreover the mechanical properties of the materials can be kept reliable at the high temperature of above 10000.
Results and Discussion The mechanical properties of Si3N4 ceramic tool materials and Si3N4/TiN nanocomposites tool materials are illustrated as a function of temperature at the holding time of 40min and pressure of 30MPa in Fig.1.
The hardness of both materials increase greatly with the temperature, furthermore the hardness of Si3N4/TiN nanocomposite tool materials is improved remarkably after the temperature exceeds 1700�.
