UV-initiated functional polyacrylamide coating on quartz sand proppant with enhanced temperature and salt resistance for excellent self-suspending ability

Key Points

• Enhanced temperature resistance allows proppants to perform better in high-heat environments, increasing efficiency.
• Coatings initiated by UV light improve salt resistance significantly, yielding up to 50% better performance metrics.
• Results demonstrated through experimental analysis involving custom polyacrylamide formulations under varying temperatures.
• Improvements support the use of functional coatings in diverse industrial applications such as hydraulic fracturing.
