Under an SGER award a search will be made for ultra-low friction materials. The work is based on the premise that very smooth and very hard surfaces of materials which do not deform by dislocation movement, by cracking, or by large elastic deformation hysteresis due to molecular movement could have extremely low friction. To test this hypothesis a number of highly cross-linked, covalently bonded elastomers will be sought out and their frictional properties related to their bond structure.

根据SGER的奖项，将寻找超低摩擦材料。这项工作的前提是，材料的非常光滑和非常坚硬的表面不会因位错运动、破裂或由于分子运动而产生的大弹性变形滞后而变形，因此可能具有极低的摩擦力。为了验证这一假设，我们将寻找一些高度交联、共价键合的弹性体，以及它们的摩擦性能与它们的键结构有关。
