Abstract: This study was aimed to explore the synthesis of sol titanium dioxide and silver nanoparticles (TiO2-AgNPs) to develop rubber latex pillows according to ergonomics so that they possess self-cleaning properties and antibacterial activities to relieve acid reflux and enhance the ability to remove any dirt or bacteria. TiO2-AgNPs at AgNP concentration of 10 ppm coated on the surface of rubber latex ergonomic pillows were found the most suitable concentration that was effective for self-cleaning and MRSA inhibition. Self-cleaning properties were measured by the degradation of methylene blue for 90 minutes, TiO2-AgNP coated samples at AgNP concentration of 10 ppm degraded 44.2% of methylene blue under UV-A light, while samples not coated with TiO2-AgNP degraded 2% of methylene blue. Samples coated with TiO2-AgNP at AgNP concentration of 10 ppm were tested for inhibition of MRSA by the agar well diffusion method. Results showed the highest inhibition radii of 4.5 mm. Skin contact allergy patch tests in 20 volunteers showed no skin symptoms. According to the satisfaction analysis, the use of self-cleaning and antibacterial anti-reflux rubber pillows yielded a relatively high level of satisfaction ( = 4.19, S.D. = 0.46), compared with that of general rubber pillows.
