The invention provides a preparation method and application of double-end-group functionalized bionic rubber. The preparation method comprises the following steps: (1) preparing an isoprenyl triblock
copolymer from a conjugated
monomer containing side group double bonds,
isoprene and a hydroxyl
isoprene precursor protected by
alkyl aluminum under the action of a
rare earth catalyst; 2) modifying polar hydroxyl of the
copolymer obtained in the step 1) by using a
phospholipid compound to obtain single-ended
phospholipid functionalized polyisoprene; 3) chemically modifying side group double bonds of the triblock
copolymer obtained in the step 2) by using a
thiol compound containing amino or / and hydroxyl through
thiol-ene click to obtain amino or / and hydroxyl modified
phospholipid functionalized polyisoprene; and 4) initiating anhydride ring-opening
polymerization by the amino group or / and hydroxyl group introduced in the step 3), and introducing a polypeptide structure into a block at one end of the triblock copolymer to obtain the polypeptide and phospholipid double-end functionalized bionic rubber which has high tensile
breaking strength and high 300% stress at definite elongation.
