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.

There are various magnetic loss materials, such as ferrites, carbonyl iron, alloy, and so on.
The main draw back of these materials is that they are heavy.
