Shape-stabilized phase change material/nylon composite based on recycled diatomite
In this study, waste diatomite from the brewing industry was first purified by heat treatment to recover its pore size and surface area. Subsequently, the purified diatomite (PD) was utilized to prepare environmentally friendly polyethylene glycol (PEG)/diatomite shape-stable phase change material (...

PD shows a high surface area of 59.41 m2g-1 and low organic impurities (<1%). PEG/diatomite SSPCM shows a high latent heat of 45.62 Jg-1 and melting peak at 34.4 °C, and exhibits excellent stability after 50 cycles. After adding the SSPCM to nylon, the results show that a composite containing 7 wt% SSPCM has the best impact and tensile strengths of 54.89 J/m and 45.95 MPa, respectively. The thermo-regulating test reveals that the inner temperature of the space can be reduced from 34.9 °C to 32.7 °C by the addition of 7 wt% SSPCM to nylon. Moreover, antibacterial test analysis shows that the antibacterial activity of nylon composites reached over 96% by the addition of 7 wt% of either PD or SSPCM, indicating that the SSPCM/nylon composites have a good antibacterial effect and can be employed in thermo-regulating textiles.
