Using cation amino polysiloxane emulsion(ASE) and anion carboxyl polysiloxane emulsion (CSE) as materials, mixing ASE and CSE together to self-assemble or aggregate by electrostatic interaction, supramolecular compound emulsion (ASE-CSE) was formed.
Introduction The use of molecular self-assembly can not only obtain the molecular aggregates of higher order structure, but also construct the bionic materials, optoelectronic information materials and supramolecular liquid crystals[1,2].
Experimental Materials and Reagents.
Silicon wafers, kindly provided by Songjiang Silicon Material Ltd., Shanghai, China, were cleaned and dried based on our previous works[5,7].

It can negatively impact mechanical properties, corrosion resistance and other useful physical properties of materials.
This effect can cause engineering materials to underperform under service condition [1], leading to possible catastrophic failure.
The thermophysical properties of materials used in this work are those given in Reference 1 and 8 for Al-4.5%Cu.

The present paper focuses on the extensive use of basalt and carbon fiber (Uni-directional) reinforced materials.
The physical properties of thermoplastic materials vary because of ambient temperature.
Hardness is used to determine the relative hardness materials, usually plastic or rubber.
The use of epoxy as matrix and adding of different materials with better properties increases mechanical properties.

(2) Where n represents the number of types of building materials; represents the total weight or number of the -th building materials, represents the -th building materials’ EEEF intensity; represents the -th building materials’ attrition rate in the construction process
(3) Where n and have the same meaning with them in equation (2); represents the -th building materials’ transport distance from production area to construction site; represents the transportation EEEF intensity of the -th building materials; represents the total weight or number of the -th building materials in demolition process; represents the -th building materials’ transport distance from demolition site to disposal area; represents the transportation EEEF intensity of the -th building materials from demolition site to disposal area .
Therefore, the original building's material retention rate η (the ratio of amount of retained material in the process of adaptive reuse to the amount of original building materials) is introduced.
Construction the model of As lack of statistical data, it is assumes that the average recovery rate for building materials after the main structure of the building was demolitioned are 90%, 50%,20%,10% and 0%for metal, brick, wood and cement and other building materials, respectively.
