Abstract

Mechanical dispersion was used to modify ethyl cellulose with the particles of bentonite clay. The prepared ethyl cellulose/bentonite composite film materials were characterized by optical microscopy and X‑ray diffraction. The thermal behaviors of both the films and the initial polymer powder were studied by using differential scanning calorimetry. It was found that the introduction of bentonite reduced the characteristic temperatures of glass transition and melting of the polymer material.

Notes

  1. In a number of publications, for example, in the book Physics of Polymers (Bartenev, G.M., Frenkel, S.Ya. Khimiya, 1992, p. 432), a similar parameter is called the “softening temperature.”
