Effects of Surface Modification with Stearic Acid on the Dispersion of Some Inorganic Fillers in PE Matrix

Round 1

Reviewer 1 Report

In this paper the novelty is not enough: it is the modification of another inorganic fillers with stearic acid. My other comments are as follows:

1. Figur 1: the descriptions of the axis are not visible.
2. All signals visible on FTIR spectra should be described not only for stearic acid and some for modified silica.
3. More details should be given as regards FTIR experiments: were the samples as KBr tablets or ATR or other?
4. It is difficult to interpretate SEM images as regards dispersion of modified and unmodified fillers.
5. The Authors should have agreement to use Figure 4.
6. Table 1.: the error should be given. THe thermal properties are acctually unchanged.

Author Response

Dear Reviewer,

First of all, we would like to thank you very much for your comments on our manuscript.

We are very sorry for sending the manuscript back late.

We fixed the manuscript as you suggested:

- Clarified the axis of the FTIR spectra

- Described in detail the FTIR experiment for each sample type

- Described other peaks in the spectra of unmodified and modified bentonite and silica

- Enlarged SEM images of samples for easy tracking

- Fixed thermal properties as you suggested

We look forward to receiving further your comments to improve our manuscript.

Best regards,
