The rheological characterisation of viscoelastic materials undergoing a sol-gel transition at the Gel Point (GP) has important applications in a wide range of industrial, biological, and clinical environments and can provide information regarding both kinetic and microstructural aspects of gelation. The most rigorous basis for identifying the GP involves exploiting the frequency dependence of the real and imaginary parts of the complex shear modulus of the critical gel (the system at the GP) measured under small amplitude oscillatory shear conditions. This approach to GP identification requires that rheological data be obtained over a range of oscillatory shear frequencies. Such measurements are limited by sample mutation considerations (at low frequencies) and, when experiments are conducted using combined motor-transducer (CMT) rheometers, by instrument inertia considerations (at high frequencies). Together, sample mutation and inertia induced artefacts can lead to significant errors in the determinatio...

使用组合电机-传感器流变仪研究凝胶系统的增强型流变仪惯性校正程序 (ERIC)

在凝胶点 (GP) 处经历溶胶-凝胶转变的粘弹性材料的流变学表征在广泛的工业、生物和临床环境中具有重要应用，并且可以提供关于凝胶化的动力学和微观结构方面的信息。确定 GP 的最严格基础包括利用在小振幅振荡剪切条件下测量的临界凝胶（GP 处的系统）的复剪切模量的实部和虚部的频率依赖性。这种 GP 识别方法需要在一系列振荡剪切频率上获得流变数据。此类测量受到样品突变考虑因素（低频）的限制，并且当使用组合电机-传感器 (CMT) 流变仪进行实验时，出于仪器惯性的考虑（在高频下）。总之，样品突变和惯性引起的伪影会导致测定中的重大错误……
