1. Research direction needed:
(1) Preparation of flexible ultra-high barrier materials and study of their penetration mechanisms, aiming to study the preparation of flexible (transparent or non-transparent) packaging film materials with a water vapor permeability (WVTR) of 10-4-10-6 g/(m2 day).  (2) Flexible fibrous (energy and optoelectronic) device packaging materials and process research aimed at breaking through the material and process challenges of device packaging evolution from planar to fibrous, enabling highly reliable packaging of flexible fibrous devices.

2. Recruitting requirements:
(1) People who have obtained or will receive a Ph.D. in materials, physics, chemistry and other related disciplines.
(2) People who understand high-barrier polymer materials, familiar with multilayer/composite barrier film materials, master dry/wet nano-coating technologies (such as ALD, evaporation, sputtering, sol-gel, etc.). People with packaging materials and process experience in the field of OLEDs and organic solar cells are preferred.
(3) People who have strong independent ability to carry out innovative work and are full of responsibility and team spirit.

3. Remuneration
(1) Treatment salary and benefits are implemented with reference to the postdoctoral policy of Fudan University with an annual salary of ¥150,000-200,000. Outperformers will have additional rewards.
(2)PENG group encourages and supports the postdoctoral researcher to apply for Shanghai Postdoctoral Fund, Chinese Postdoctoral Fund, National Natural Science Fund, etc. in accordance with relevant national and local policies.
(3) Outperformers can continue to work in Department of Macromolecular Science or Laboratory of Advanced Materials through the introduction of talents 1-3 years later. They can join Fudan University to edit the teacher's sequence, enjoy housing allowance and higher wages and benefits. For details, please refer to talent introduction and remuneration standard of Fudan University.
