design and fabrication of advanced elastomer nanocomposites towards extremely energy-saving tires based on macromolecular assembly strategy

主讲人 : 张立群

energy use due to automobile tires accounts for more than 6% of the world’s total energy consumption and ~5% of all carbon dioxide emissions. we designed and fabricated a next-generation, energy-saving advanced elastomer (ae)  d on a macromolecular assembly strategy. this ae delicately balances rolling resistance, wear resistance and wet-skid resistance, addressing the so-called “magic triangle” that has plagued the tire industry for more than century. this ae cross s anionically synthesized hydroxyl-terminated solution-polymerized styrene-butadiene copolymers with highly symmetric isocyanates and polyols to generate a uniform network by macromolecular self-assembly. remarkably, compared with those of widely commercialized elastomer nanocomposites tailored for “green tires”, the wear resistance, rolling resistance and wet-skid resistance of this ae are improved by 94.6%, 69.8% and 13.8%, respectively. this ae affords a new opportunity for the large-scale application of next-generation high-performance automobile tires that will, in part, resolve a serious global energy and environmental crisis.
