摘要

A novel, semi-crystalline poly(1,4-cyclohexylenedimethylene terephthalate-co-1,4-cyclohexylene dimethylene 2,6-naphthalenedicarboxylate) (PCTN) copolyester was synthesized and successfully extruded using an extruder attached with T-die. The extruded sheet was uniaxially cold-drawn into film at 150 degrees C, a temperature between glass transition temperature and melting temperature. The mechanical, thermal, thermo-mechanical, water barrier, and optical properties of developed film were characterized. Orientation of different phases was analyzed by X-ray diffraction. The actual chemical composition of PCTN copolyester was analyzed by nuclear magnetic resonance spectroscopy. Our results clearly indicated the thermal, dimensional stability, mechanical, and water barrier properties of PCTN films increased in a linear trend with draw ratio. It was also found that PCTN film has better water barrier property compared to conventional poly(ethylene terephthalate) (PET) and poly(ethylene 2,6-naphthalate) (PEN) films. Based on the exceptional performance properties, novel PCTN film may find a strong position as a substrate for next generation flexible electronics among various performance materials.
