1. Industry Background and Technical Principles
1.1 Core Demand for Disinfection Spray Technology
The frequent occurrence of global public health events (such as the COVID-19 epidemic) has driven a surge in demand for disinfection products. Traditional disinfection sprays have problems such as residual ingredients, weak surface adhesion, and short antibacterial time. According to statistics in 2025, the global surface disinfectant market size has reached US$42 billion, of which the proportion of sustained-release disinfectants containing polymer materials has increased to 28%.
1.2 Technical characteristics of NVP homopolymer
N-vinyl pyrrolidone (NVP) homopolymer (PVP) is prepared by free radical solution polymerization, and its molecular structure has the following advantages:
Strong adhesion: PVP side chain hydroxyl groups form hydrogen bonds with the surface of objects, enhancing the adhesion of disinfectant ingredients;
Film-forming property: Forming a transparent film on the surface of objects, extending the sustained release period of disinfectants to more than 24 hours;
Biosafety: Complying with ISO 10993 standards, non-irritating and non-toxic to the mouth.
1.3 Mechanism of action
NVP homopolymer improves the performance of disinfectant spray through the following pathways:
Adhesion enhancement: Fixing quaternary ammonium salts, peracetic acid and other disinfectant ingredients through intermolecular forces to reduce volatile loss;
Sustained and controlled release: The film structure slowly releases active ingredients to achieve long-term antibacterial effects (such as the inactivation rate of the new coronavirus >99.99%);
Broad-spectrum compatibility: It can be compounded with ethanol, chlorine dioxide, double-chain quaternary ammonium salts and other ingredients to meet the needs of multiple scenarios.
2. Innovation and breakthrough of key technologies
2.1 Supercritical CO₂ green synthesis process
The supercritical CO₂ polymerization technology developed by Qingji New Materials realizes the efficient preparation of NVP homopolymer:
The monomer conversion rate is increased to 99.5%, and the residual monomer content is <0.1ppm;
Energy consumption is reduced by 40%, which meets the EU REACH environmental protection standards.
2.2 Nanocomposite enhancement technology
Jiankai Technology combines nanosilver particles with PVP to launch Ag-PVP disinfection spray:
The sterilization efficiency is increased by 3 times (the inactivation time of E. coli is shortened from 5 minutes to 1.5 minutes);
The adhesion is enhanced by 50%, which is suitable for porous surfaces such as metal, plastic, and fabric.
2.3 Thermosensitive smart spray
Thermosensitive PVP copolymer (PLGA-PVP) developed by Borealis can trigger drug release at 25℃~40℃:
The antibacterial activity is automatically enhanced in high temperature environment (such as the surface of medical equipment);
The ingredients are kept stable when stored at low temperature, and the shelf life is extended to 18 months.
3. Clinical application and efficacy data
