Effect of polydimethylsiloxane and polyol molecular weight on properties of polyurethane |
| 초록 |
Polydimethylsiloxane-polyurethane(PDMS-PU) was synthesized using MDI, polyethylene glycol and these types of siloxane polyol. The dependance of siloxane molecular weight on the mechanical and surface properties was confirmed by UTM and contact angle and SEM. PDMS-rich phase at the polymeric surface enhanced the increase in hydrophobicity. Contact angle of PDMS-PU was increased with increasing PDMS molecular wieght. The hydrophobic effect of PDMS blocks in PDMS-PU matrix control level to the potential water-barrier property. The optical transmittance and water vapor transmission rate of PDMS-PU were also investigated to use as an encapsulation material for the environmental protection and industrial applications |
