碩士 / 朝陽科技大學 / 應用化學系 / 106 / In this study reports on the functionalization of recycled diatomite for preparing green and shape-stabilized phase change material (SSPCM); the SSPCM can be employed in Nylon to form thermo-regulating textiles. To avoid PCM leakage, PCM is adsorbed on diatomite with a stable structure. The purified diatomite(HD)adsorbs polyethylene glycol(PEG) by the straight dipping process for producing SSPCM. HD shows a high surface area of 58 m2g-1 and low organic impurity (<1%); the PEG/P-DT SSPCM exhibited high latent heat of 45 Jg-1 and low leakage (<0.2%). The thermal cycling test also showed excellent stability after 50 cycles. By adding SSPCM into the Nylon, the composite improved the 5% decomposition temperature (Td5) from 426.3oC to 442.1oC. The composite NCPCM7 exhibited impact and tensile strengths of 54.89 J/m and 45.95 MPa, respectively. The water absorption test results show that the addition of diatomite can increase the water absorption of the composite material. Moreover, NCPCM7 can reduce the temperature from 34.9 oC to 32.7 oC. Antibacterial test analysis, the antibacterial potential of the composite material reached more than 96%, with good antibacterial effect.
