Many more percolation pathways form for enhanced conductivity, but the materials become to be porous and weak [3].
As a result, composite plate materials with high graphite content are extremely brittle, and have poor gas barrier properties.

Introduction Diamond saw as an important cutting tool has been widely used in the processing of stone, glass, iron and other materials, but the vibration and noise produced by these tools cause great harm to the environment.
The damping sandwich circular saw is pasted with a layer of viscoelastic material, energy dissipation of the damping material is used to reduce vibration and noise[1].Now the damping sandwich circular saw mostly uses viscoelastic damping materials, it has good effect of vibration and noise reduction, but it has Short Service life, damping material can easily deteriorate for high temperature in sawing process, so material silencing effect is reduced.
When the deleted volume of damping materials is at around 45%, circular saws meet the established rigid conditions, achieves the best topology structure, and this curve can compute the damping materials delete rate approximately, which can make approximate evaluation on the damping material coverage.
So, with the same amount of damping materials, select the optimal topological structure to fill with damping material, which can make the damping loss factor maximum and the vibration and noise reduction effect best.

Chitosan application has a huge market in the food, pharmaceutical, water treatment, cosmetic and functional materials and other fields[2].
It become a hot topics of current research by using natural plant crystalline cellulose as chitosan reinforcement fiber to develop a lightweight, high-performance, low-cost, fully biodegradable materials[3]。
In this study, corn stalk cellulose microcrystal was prepared, corn stalk microcrystalline cellulose/chitosan composite film materials were prepared, and the thermal stability and mechanical properties of composite film were investigated.
Experiment Materials Corn stalk, taken from the corn field；Chitosan was provided by Jinan Dai gang biological science co., Ltd.; Ammonium ferrous sulfate and other reagents were all analytical reagent.
