As a new functional material, it can be used as carrier transport material or luminescent material in small devices [2, 3].
The effects of the following variances on product structure were detected: (1) in the same ratio of raw material and the synthesis temperature, with different kinds of solvent, hydrohalogen acid, dehydrated alcohol, methanol, and DMF were chosen as the solvent. (2) In the same solvent and synthesis temperature, with different ratio of raw materials, the matching corresponding to uniform data points during the scale of C4H9NH3Br:CH3NH3Br:CuBr2=2:1:2~2:3:2 were chosen; The product after reaction was performed with characterization test through filtration and vacuum drying.
When the ratio of raw materials was 2:2:2, relative intensity of the new peak in synthetical product was larger compared that of other ratio.

The solid biomass fuels with crop straw, tree branches, leaves and Forestry three remaining items and other wastes as raw materials has the advantage of" "Easy access, clean, green, flammable "[3], it can not only ease the pressure of energy shortage, and also can reduce the amount of greenhouse gases as well as hydrogen sulfide and other toxic gas emissions.In China, solid biomass energy fuel instead of traditional energy sources to a great extent, and has a better economic and environmental benefits, but the farmers their demand is not high, which seriously hindered the development of the industry [4-5].In order to promote the rapid progress of the industry to improve the structure of rural energy, protect the environment, you first need to understand the wishes of the farmers demand for robust biomass energy.
Government should increase the subsidies for farmers to use solid biomass energy,including the construction of ancillary facilities and subsidies for the purchase of raw materials, to inspire households to change the energy structure;(2)the concept of product positioning and promotion: In the marketing process, using television, newspapers, billboards and other forms of promotional activities,to publicity its environmental and safety,to expand the influence of solid biomass energy in rural households and promote solid biomass fuels industry.

Low rates of scrap and rework lead to lower costs for material, energy and personnel.
The results were then discussed and reviewed in expert interviews arranged as part of the research project with representatives from science and industry.
Poorer material quality will reduce product quality which has a negative effect on the quality target.
Higher rates of scrap and rework provoke additional material and energy costs as well as personnel costs.
