Based on the structural elements of mussel adhesive protein, the group of WAN Xiaobo at CAS Qingdao Institute of Bioenergy and Bioprocess Technology (QIBEBT) produced analogues based on PVP and catechol groups which, after underwater curing, reached a bonding strength of 1.6 MPa. After substituting PVP by PVA and heating at 140 ℃ for 20 min, a bonding strength of up to 17.3 MPa was achieved.
