AI Technical Summary
Existing drug container coatings lack stability and chemical stability at high pH values, and are prone to interactions, especially when storing biological products, which can affect the storage capacity of drug compositions.
Plasma pulsed chemical vapor deposition (PECVD) is used to coat a glass surface with a specific precursor. By controlling the process temperature and pulse duration, and combining pretreatment processes such as water washing and plasma pretreatment, a coating with excellent adhesion and high chemical stability is formed.
It provides tolerance and stability over a wide pH range, reduces the interaction between the drug container and the drug composition, improves the stability and alkali resistance of drug storage, and has a thin and durable coating.
