The slide-ring (SR) effect in composite materials is demonstrated by comparing the mechanical properties of plasma-modified boron nitride (p-BN)/SR elastomers and p-BN/fixed crosslinked (FC) elastomer composite materials that include a large amount of plasma-surface-modified BN (∼56 vol%). The toughness of p-BN/SR was ∼7 times that of p-BN/FC. Such SR effect was not observed in the raw BN/SR composite material but only in the p-BN/SR composite material. Time-domain nuclear magnetic resonance measurements suggested that the plasma-surface modification of BN formed crosslinking points to the SR and suppressed the decrease in the molecular mobility of SR in the composite materials.

可移动交联点对大量等离子体表面改性氮化硼与滑环弹性体复合材料力学性能的影响

通过比较等离子体改性氮化硼 (p-BN)/SR 弹性体和 p-BN/固定交联 (FC) 弹性体复合材料的力学性能，证明了复合材料中的滑环 (SR) 效应等离子表面改性的 BN (~56 vol%)。p-BN/SR 的韧性是 p-BN/FC 的 7 倍。在原始 BN/SR 复合材料中未观察到这种 SR 效应，而仅在 p-BN/SR 复合材料中观察到。时域核磁共振测量表明，BN 的等离子体表面改性形成了与 SR 的交联点，并抑制了复合材料中 SR 分子迁移率的降低。
