Q: Does the material profession belong to chemical or chemical class?: Belong to chemical class

Q: What are the basic knowledge of the basic course of material chemistry?: Polymer chemistry, chemical chemistry, chemical science, physical chemistry, chemical chemistry, materials chemistry, polymer alloys, functional materials, chemistry and physics, crystal growth, chemical engineering, Composite materials and so on.

Q: Just finished college entrance examination, more interested in chemical disciplines, such as pharmaceutical, food science, materials, these aspects. Do not know which of these employment situation is better, how to pay and work comfort. Thank you can be added. (Note: I am two undergraduate): Graduates of chemistry, work tired, low starting wages, poor working environment.

Q: Like we ordinary people how to buy some chemical materials, usually where?: Chemical reagents shopping malls are everywhere, we are Huadonghuahua glass, call to send, it can not find a lot of online. National control such as sulfuric acid, nitric acid and other public security bureau seems to require proof. It is not a scientific research institution school class is difficult to buy.

Q: Was a literally raised for several years of school admission, transfer to the material chemistry. High school physics and chemistry is very poor, no interest, learn very laborious. And this is the school opened a new professional, I heard that this is to contact a lot of harmful substances. Feeling very difficult to learn is not suitable for me, after the employment is also a problem. I would have wanted to learn accounting like the degree of professional, learn this fear is to hang the branch.: Girls in the choice of professional time not too biased in science, science girls work is not easy to find! Material chemistry is generally a number of polymerization-like reactions, but also need to use organic reagents, the girl's body is harmful! If you can avoid contact. But also in employment is also limited, and there may be gender discrimination.

Q: What can I do after the chemistry of materials? The I am learning this, please shrimp pointing: There is no material in life, you think about it, construction, daily necessities, bedding, computers, radios and so on.

Q: What is the difference between material chemistry and polymer chemistry in chemistry?: The basic material chemistry is a simple understanding of the chemical materials, and materials include: inorganic materials, metal materials, organic materials, synthetic materials, and polymer materials refers to the synthesis of polymer materials with organic compounds, so the chemical range of materials Relatively wide, more focused on inorganic chemistry, which is focused on inorganic materials, metal materials research,

Q: What is the main work of the chemistry of materials after graduation?: Technical route growth route: technician → engineer → chief engineer (or entrepreneuri

Q: What are the chemical materials?: Functional polymer materials mainly include the physical function of polymer materials and chemical function of polymer materials.The former are such as conductive polymer, polymer semiconductor, photoconductive polymer, piezoelectric and thermoelectric polymer, magnetic polymer, optical polymer, liquid crystal Polymer and polymer materials, etc .; the latter, such as reactive polymers, ion exchange resins, polymer separation membranes, polymer catalysts, polymer reagents and artificial organs, in addition to biological functions and medical polymer materials, Such as biopolymers, simulators, macromolecules and artificial bone materials.
