Introduction In recent years, with the continuous development of science and technology, the research and development of new materials become more and more comprehensive, and gradually develop and promote some polymer materials [1].
However, most of these polymer materials are brittle materials, which often have defects in the preparation process.

Layered Composite Materials Designed for Higher Corrosion Resistance of Oil Production Equipment N.A.
Lining consists in simultaneous expansion of pipes made of dissimilar materials, which possess different properties.
In the world practice, these materials have found application in many industries.
Among the known methods of manufacturing pipes from layered composite materials, lining should be distinguished.

But and of the nanoporous materials are unknown.
In order to obtain and, the FEM for the solid materials of nanoporous materials are made (shown in Fig. 3 and Fig. 4).
The size of the two models is the same to the one of the nanoporous materials.
In the solid FEM, the materials properties for the solid materials and the Si substrate are given out in Table 2.

Impact of pH Value and Temperature on Cement-based Materials Adsorbing Heavy Metal Ions Yali Wanga*, Suping Cuib, Xikui Xuc, Mingzhang Land College of Materials Science and Engineering, Beijing University of Technology, 100 Pingleyuan, Chaoyang District, Beijing 100124, China.
Micro-structure analysis shows that cement-based materials’ main adsorption methods are different when pH values are different.
Permeable pavement materials can discharge the rainwater very fast and prevent surface accumulated water.
Summary Cement-based materials have selective adsorption phenomenon for different heavy metal ions (Cu2+, Zn2+, Pb2+, Cd2+).In addition to zinc ions, the cement-based materials’ capacity of adsorbing heavy metal ions increases as the pH value and the temperature increase.
