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?: Go to school to ask the chemical equipment teacher to prove that you can buy in the chemical shop

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.: It is worth, undergraduate university is very important, 211 / / 985 school employment or Kaoyan will have a lot of convenience, the original school chemistry is not easy to find a job and hurt the big.

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?: There are very different materials chemistry more focused on inorganic chemistry, and polymer materials more focused on polymer chemistry, mainly polymers, such as fiber, rubber and the like, and some relationship with organic chemistry, are generally partial engineering.

Q: What is the main work of the chemistry of materials after graduation?: Compound route growth route: logistics practitioners → logistics director → chemical enterprise logistics director → chemical enterprise logistics director

Q: What are the chemical materials?: Whether it is as a food protein or as a cotton fabric, wool and silk are natural polymer materials, even the body itself, basically also by a variety of biological polymers. China in the development of natural polymer materials have been walking The world's leading level. The use of bamboo, cotton, linen and other polymer materials such as fiber paper is one of the four ancient inventions in ancient China.In addition, the use of tung oil and large paint and other polymer materials as paint, paint paint products are ancient Chinese tradition technology.
