Freestanding ultrathin glass film (UGF) of 45S5 bioglass was successfully bonded on a Ti substrate by the room‐temperature bonding method. 45S5 UGFs with a thickness of 1~4 μm were fabricated by the glass‐blowing technique, and the UGF was attached on the Ti plate at room temperature with a water layer between them. The bonding strength was about 370 mJ/m² just after bonding, and it increased during storing in the ambient atmosphere at room temperature and reached about 900 mJ/m² after 9 hours storage. The interfaces of the UGF and Ti substrate during the bonding process were analyzed by an X‐ray photoelectron spectroscopy. The as‐prepared UGF was found to have surface layers with a high content of Na₂O and low content of SiO₂, and the dissolution of Na₂O‐rich component into water layer induced depolymerization and polymerization of SiO₂ network to form Si‐O‐Si bonds between the UGF and Ti plate and then to increase the bonding strength during storage. This work presents the simple technique to laminate the bioactive glass layer on the surface of the metal without post heat treatment.

通过溶解-聚合反应在钛上生物活性超薄玻璃膜的室温粘合方法

通过室温粘合方法将45S5生物玻璃的独立式超薄玻璃膜（UGF）成功粘合在Ti基板上。通过吹玻璃技术制备了厚度为1〜4μm的45S5 UGF，并将UGF在室温下附着在Ti板上，并在其间形成水层。刚粘合后，粘合强度为约370mJ / m ²，在室温下于环境气氛下保存时增加，在保存9小时后达到约900mJ / m ²。通过X射线光电子能谱分析了键合过程中UGF和Ti衬底的界面。发现制备的UGF具有高Na ₂ O含量和低SiO ₂含量的表面层。，然后将富含Na ₂ O的成分溶解到水层中，引起SiO ₂网络的解聚和聚合，从而在UGF和Ti板之间形成Si-O-Si键，然后增加存储期间的键合强度。这项工作提出了一种简单的技术，可以在不进行后热处理的情况下将生物活性玻璃层层压在金属表面上。
