Cellulose From Sea Squirt Or New Energy Saving Material

< p > the sea squirt used to be used only as food, and its capsule can not be eaten but abandoned.

The cellulose produced by the sea squirt is in the capsule of the sea squirt.

How to turn waste into treasure? This topic has become the research direction of the research group. Now, the sea sac, which has been thrown away as garbage, has become the raw material for developing new industries.

< p > according to Zhang Dawei, since his discovery of cellulose in 2009, his team has broken through a number of key technologies, developed new special functional materials such as the energy saving reflective film of sea squirt cellulose, the high-performance conductive paper of sea squirt cellulose, and the fibrin spinning liquid of the sea cucumber and so on. With the cellulose as the origin, the antenna has been extended to many fields in the country, and has obtained 7 national invention patents.

The production of a series of new industries will be driven by the cellulose products of the sea squirt. The application of new technology will also bring more economic benefits to enterprises and individuals.

< p > studies have shown that ASP cellulose has many unique characteristics compared with plant cellulose.

For example, more than 90% of the former is I beta, and its crystallinity is high, while the latter has only 50% to 70% I beta crystal form.

At present, there are only reports on the extraction of marine drugs from sea squirt in China.

Zhang Dawei said.

Besides, P can also form cholesteric liquid crystals at certain concentrations.

Cholesteric liquid crystals have excellent optical properties, such as optical anisotropy, birefringence and selective reflectivity. Zhang Dawei believes that this project is expected to be used in the fields of < a href= "//www.sjfzxm.com/news/index_c.asp" > anti-counterfeiting materials < /a >, decorative coatings, reflective color electronic paper and so on.

After 4 years of research, Zhang has successfully prepared nanoscale cellulose, and studied the morphology and structure of the cellulose by polarized light microscope, infrared spectrometer, atomic force microscope and scanning electron microscope (P).

The results showed that the powder of the prepared sea squirt cellulose sample was almost I beta crystal. The nanoscale cellulose of the sea squirt was a rod like structure with a uniform diameter, the average diameter was about 30nm, and the length was between 200nm and 2 m.

Zhang Dawei also found that when the fibrin suspension reached a certain concentration, it could spontaneously form cholesteric liquid crystals, and cholesteric liquid crystal films had a selective reflectivity and showed a rainbow like color in the natural light.

< p > industry experts have said that in the field of science and technology, the achievement of industrialization is often faced with the embarrassing situation of "reality and bone".

However, the technology of sea shell cellulose spinning technology developed by Zhang has solved the problem of pformation of achievements.

The new marine garments made from sea cucumber cellulose have successfully captured the hearts of Qingdao enterprises.

< p > cellulose is the main production of clothing less than a href= "//www.sjfzxm.com/news/index_c.asp" > raw material < /a >. The molecular weight of sea squirt cellulose is 2.5 times higher than that of cotton cellulose. Therefore, its strength is higher than that of cotton cellulose, and its permeability and thermal stability are good, non-toxic, harmless and safe. It can be biodegradable and helps to save energy and protect environment.

Zhang Dawei said that such clothing is less irritating to the human body and more comfortable for people to wear.

< p > Qingdao snow Group Co., Ltd. will work with R & D team to develop high value added sea cucumber cellulose spinning and clothing products.

At present, the project has entered the pilot stage, and it is expected to achieve large-scale production in 2015.

< p > in addition, < a href= "//www.sjfzxm.com/news/index_c.asp" > sea squirt cellulose < /a > can also be applied to the medical field.

Zhang Dawei said: "most commonly used medical gauze is made of cotton cellulose.

Compared with cotton cellulose, the sea cucumber cellulose has excellent mechanical properties and biocompatibility. Therefore, medical gauze made from sea cucumber cellulose will accelerate at least 20% of the wound healing.

In the future, the use of sea squirt cellulose may also recognize the authenticity of the RMB P.

"The strength of the renminbi is not very high now. In Australia, New Zealand and other countries, plastic materials have been used instead of traditional paper currencies. They can not only be recycled, but also contain unique anti-counterfeiting techniques."

Zhang Dawei said, "the use of sea squirt cellulose as raw material of RMB can not only increase strength, but also replace the existing anti-counterfeiting technology of RMB and bonds, making it easier for people to distinguish authenticity."

However, as the RMB security involves a number of integrated technologies, Zhang stressed that through some related technologies, some technology can be replaced.

But whether it is feasible or not is still unknown.

< p > after 4~5 research and development, the application technology of sea shell cellulose in home textiles, papermaking and energy saving materials has been recognized more and more. It has broad prospects in the fields of high-grade textiles, reflective pparent non-woven fabrics, anti-counterfeiting materials, decorative coatings, display materials and infrared shielding materials.
