摘要:

以二月桂酸二丁基锡(DBTDL)为催化剂, 微晶纤维素为骨架材料, 二乙二醇正十六烷基醚(E2C16)为相变材料, 采用化学接枝法制备了系列纤维素丙酸酯-g-二乙二醇正十六烷基醚(CP-g-E2C16)固-固相变材料. 利用傅里叶变换红外光谱(FTIR)、 核磁共振氢谱(1H NMR)、 差示扫描量热仪(DSC)、 热重分析(TG)和X射线衍射(XRD)对CP-g-E2C16相变材料的结构和热性能进行了表征. 结果表明, 得到了E2C16的取代度和接枝含量分别为0.12~0.37和17.1%~33.4%的CP-g-E2C16固-固相变材料. CP-g-E2C16接枝共聚物的相变温度和相变焓分别为25~34 ℃和40~62 J/g, 符合人的体感舒适温度范围. CP-g-E2C16固-固相变材料的耐热温度高于237 ℃, 与E2C16相比提高21~40 ℃, 有望应用于熔融纺丝法制备纤维素基储热调温纤维领域.

Abstract:

A series of cellulose propionate-g-diethylene glycol hexadecyl ether(CP-g-E2C16) solid-solid phase change materials was prepared by chemical grafting method with dibutyl tin dilaurate(DBTDL) as the catalyst, cellulose as the matrix material, diethylene glycol hexadecyl ether as the functional substance. The structure, phase change properties and thermal stability were characterized using Fourier transform infrared spectroscopy(FTIR), hydrogen nuclear magnetic resonance spectrum(1H NMR), differential scanning calorimetry(DSC), thermogravimetric analysis(TG) and wide-angle X-ray diffraction(XRD). The results showed that CP-g-E2C16 solid-solid phase change materials were prepared. CP-g-E2C16 copolymers with different feeding ratios, substitute degree and grating percents of E2C16 are in the range of 0.12—0.37 and 17.1%―33.4%, respectively. The onset melting temperatures of CP-g-E2C16 are in the range of 25—34 ℃, the melting enthalpy increases from 40 to 62 J/g. The thermal resistant temperatures of CP-g-E2C16 are all higher than 237 ℃, which are 21—40 ℃ higher than E2C16. All the products show good temperature-adjusting performance for solid-solid phase transition, which is expected to be used in cellulose-based thermo-regulating fiber field.
