Mettler-Toledo DSC

The composites as well as the nanowires were characterized by several techniques. Scanning electron microscopy (SEM) images and energy dispersive analysis of x-rays (EDAX) were obtained with a Leica S-440I microscope fitted with a Link ISIS spectrometer. Infrared (IR) spectra were recorded on small pieces of the samples embedded in KBr pellets using a Broker FT-IR spectrometer. DSC was carried out on the samples ( 7 mg) with a scanning rate of 20 K min-1 between 120 and 260 °C using a Mettler-Toledo DSC. 

A Mettler Toledo DSC 822e equipment was used to carry out the tests. 3.5 0.5 mg of powdered specimens, in standard 40 pi aluminum crucibles, were heated under air flow (50 ml/min) at a rate of 10°C/min.

Thermal properties of PP, neat blend, MFBs and MFCs were studied using a Mettler Toledo DSC 822 at a heating and coohng rate of 5°C/min. The samples were heated up to a maximum temperature of 200°C, held there for 3 min, and then allowed to cool to room temperature to analyze the non-isothermal crystallization behavior of PP component.

I. Calibration of Thermal Lag In the Mettler Toledo DSC to compensate for thermal lags, an adjustment, denoted by Mettler Toledo as tau lag, is used. The DSC tau lag performs two compensations (1) it matches the program temperature to the reference temperature (as noted in Fig. 2.17), and (2) it adjusts for the heating rate as noted in the following equation ... 

Similar to the Mettler Toledo DSC, an advantage of the Perkin-Elmer power compensation DSC is the simplicity of its temperature calibration for any heating rate (Perkin-Elmer 1976). This was true for the sample holder of the Perkin-Ehner DSC-2, and it is true for the sample holder of the Diamond Pyris DSC, since the structure of the sample holder did not change. In general, the following equation describes the temperature calibration of a power compensation DSC on heating...

Test bar characterization. The injection-molded test bars are characterized by optical microscopy and by differential scanning calorimetry (DSC). Light microscopy is carried out in a Zeiss Axioplan 2 equipped with an AxioCam camera. The specimens are cross-sections cut from the centers of the test bars. They are 10 p,m thick. Slicing is carried out at -70 °C using a rotary cryo-microtome Leica RM 2165. A Mettler-Toledo DSC 82 P is employed. Sample mass is 5.0 0.1 mg. The samples are studied under nitrogen flux, cooled to —100 °C and heated to 280 °C at a rate of 20K/min.
