Dr. Fudan Launches Natural Polymer Cellulose Health Membrane

Zhang Lei, Ph.D., Department of Chemistry, Fudan University, won his “Boss Dream”—after he was supported by the “Angel Fund” that supported college students’ own entrepreneurship, his “Fuai Green Chemical Technology Co., Ltd.” was established in the Fudan Incubation Base recently. . Zhang Lei is very confident about the company's prospects because he has a "health product" - a "healthy film" with independent intellectual property rights.

The safety and environmental protection of plastic products has received much attention recently. The General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China (AQSIQ) held a press conference on the 25th this month to report the results of spot checks. Some PVC cling films, which are mainly used for packaging, contain plasticizers that are not permitted by the relevant national standards. Zhang Lei said that this is only one aspect of the problem. In China, the fundamental problem of plastic products is "white pollution". All kinds of plastics are buried underground and cannot be degraded and cause pollution. Zhang Lei invented the "health film" to natural polymer cellulose as raw materials, due to natural origin, not only non-toxic harmless, but buried in the ground can be fully decomposed within 3 months. It is understood that the domestic has begun to study the degradation technology of plastic products, but the so-called degradable material is only polyethylene to add some starch, and finally can only dissolve the added starch, and the plastic is still "unbreakable." Zhang Lei developed cellulosic raw materials and achieved full-scale degradation on environmental indicators.

Zhang Lei said with confidence that his new invention has both safety and cost considerations. “The market price of polyethylene is now about 10,000 yuan a ton, and the material we need is only 6,000 yuan a ton.” Currently, he The healthy film was mainly made into agricultural mulch, and the product was degraded when tested at the Agricultural College of Zhejiang University.

So can this polymer film be made into a safe cling film? Zhang Lei said: "This is the main direction for the company's next step. Now our product is not hydrophilic enough, it can not be used as cling film, but I have begun to study this issue, and strive to be resolved as soon as possible, so that really worry-free plastic Products into the life of citizens!"
