ZnO is the well-known compound, which has been used over thousands of years in various industrial fields, ranging from cosmetics and rubber to ceramics. However, by nanotechnology, ZnO nanoparticles have been produced with nanoscale size that brings new capabilities with its own unique properties. Now, let’s explore the significant differences between ZnO and ZnO nanoparticles as well as the application of the latter.
1. Size and Surface Area
- ZnO: Conventional zinc oxide is available as a bulk material with particle sizes typically in the micron range. It has a relatively low surface area compared to its nanoparticle counterpart.
- ZnO Nanoparticles: These are engineered to have particle sizes in the nanometer range (1-100 nm), resulting in a significantly larger surface area-to-volume ratio. This enhances their reactivity and functionality in various applications.
2. Optical Properties
- ZnO: Bulk ZnO is an effective UV-blocking agent but lacks the transparency required for certain applications, such as cosmetics.
- ZnO Nanoparticles: Due to their nanoscale size, ZnO nanoparticles exhibit excellent UV absorption while remaining transparent. This property makes them ideal for sunscreens and other cosmetic formulations.
3. Antimicrobial Properties
- ZnO: Conventional ZnO shows some antimicrobial activity, but its effectiveness is limited in applications requiring high reactivity.
- ZnO Nanoparticles: ZnO nanoparticles possess enhanced antimicrobial properties due to their larger surface area, which allows for greater interaction with microbial cells. This makes them more effective in healthcare and food packaging.
4. Photocatalytic Activity
- ZnO: Bulk ZnO can act as a photocatalyst under UV light, but its efficiency is limited due to its size and reduced surface area.
- ZnO Nanoparticles: ZnO nanoparticles exhibit superior photocatalytic activity, making them highly effective in environmental applications like wastewater treatment and air purification.
5. Mechanical Properties
- ZnO: As a bulk material, ZnO is widely used in rubber and ceramics for its durability and reinforcing properties.
- ZnO Nanoparticles: ZnO nanoparticles can further enhance mechanical strength and flexibility when added to composites, making them ideal for advanced materials.
6. Applications
- ZnO: Traditionally used in rubber manufacturing, ceramics, and ointments like calamine lotion for its soothing and protective properties.
- ZnO Nanoparticles: Widely applied in modern industries, including:
- Cosmetics: Sunscreens, anti-aging creams, and skincare products.
- Electronics: Transparent conductive films and sensors.
- Healthcare: Antimicrobial coatings and drug delivery systems.
- Environmental Solutions: Photocatalysts for pollutant degradation and water purification.
