Abstract

A graphene-nanoplatelet-reinforced (GNP-reinforced) UV/heat dual-curable sealant for narrow bezel displays was fabricated for seamless-design display applications. GNPs with good thermal conductivities and mechanical properties were introduced into the sealant as the organic filler to improve its adhesive strength. As the GNPs collectively act as a barrier against moisture in the sealant, the moisture permeability of the best-performing GNP-reinforced sealant was lower than that of the conventional sealant, and less internal contamination was observed due to its higher adhesion strength. The introduction of GNP improves the properties of narrow-bezel-display sealants by increasing adhesion and decreasing moisture permeability.

摘要

为无缝设计的显示应用制造了一种用于窄边框显示器的石墨烯纳米片增强（GNP 增强）UV/热双固化密封剂。将具有良好导热性和机械性能的GNP作为有机填料引入密封胶中以提高其粘合强度。由于 GNP 共同充当密封剂中的水分屏障，因此性能最佳的 GNP 增强型密封剂的透湿性低于传统密封剂，并且由于其较高的粘合强度，观察到的内部污染较少。GNP 的引入通过增加附着力和降低透湿性来改善窄边框显示器密封剂的性能。
