2,6-单取代芳香酚醛树脂及其复合膜的可逆热敏变色性能
Reversible Thermochromic Properties of 2,6-Monosubstituted Aromatic Phenolic Resin and Its Composite Film
摘要
Abstract
2,6-monosubstituted aromatic phenolic resin(IPD-BPA-TPD)was prepared by microwave-assisted method using bisphenol A(BPA),terephthalaldehyde(TPD)and isophthalaldehyde(IPD)as co-condensation monomers based on an open system and solution polycondensation method.A reversible thermochromic nickel-based butadiene rubber film was prepared using resin as a chromogenic agent.The resin was tested by a gel permeation chromatograph,a nuclear magnetic resonance hydrogen spectrometer,a nuclear magnetic resonance carbon spectrometer,a thermogravimetric analyzer and a thermal analyzer.The composite film was tested by a thermogravimetric analyzer,a thermal analyzer,a spectrophotometer and a polarizing microscope.The thermochromic properties,thermal stability,thermal cycle stability and microstructure of the film were studied.The results show that the Mˉn of IPD-BPA-TPD is 1.133×103 g/mol,the PDI is 1.005.The total color difference ΔE of the composite film reaches about 90 in the low temperature section(12～38℃)of the constant-rate cooling phase transition,and the absorption/scattering color depth difference Δ(K/S)reach about 15 and 40 in the visible regions of 480～600 nm and 600～660 nm,and film has good thermal stability and thermal cycle stability.关键词
