Materials Cover Letter: What Editors Actually Need to See
Materials editors screen for scope clarity and section fit across a broad materials-science platform. A cover letter that names the section and states a clear materials result moves fastest.

How to use this page well
These pages work best when they behave like tools, not essays. Use the quick structure first, then apply it to the exact journal and manuscript situation.
Question | What to do |
|---|---|
Use this page for | Getting the structure, tone, and decision logic right before you send anything out. |
Most important move | Make the reviewer-facing or editor-facing ask obvious early rather than burying it in prose. |
Common mistake | Turning a practical page into a long explanation instead of a working template or checklist. |
Next step | Use the page as a tool, then adjust it to the exact manuscript and journal situation. |
Quick answer: a strong Materials cover letter names the target MDPI section, states a clear materials-science result, and shows the submission is complete. The journal covers everything from metals to polymers to biomaterials, so the editor's first task is routing -- help them do it without guessing.
What the official sources do and do not tell you
The official Materials pages describe the MDPI submission workflow and list section scopes, but they do not prescribe a specific cover-letter structure.
What the journal model does imply is clear:
- the manuscript should be recognizably about materials, their properties, processing, or performance
- the editor needs to know which section the paper targets
- the letter should reduce friction in a fast editorial workflow
That means section selection and materials focus matter more here than novelty claims.
What the editor is really screening for
At triage, the academic editor is usually asking:
- is this paper about materials science, or is it a chemistry or physics paper that happens to mention a material?
- does it fit the section the author selected?
- does the submission look complete enough to send to reviewers without extra back-and-forth?
- is the contribution stated clearly enough to justify peer review?
A cover letter that answers these questions in the opening paragraph will clear triage fastest.
A practical template you can adapt
Dear Editor,
We submit the manuscript "[TITLE]" for consideration in the
[SECTION NAME] section of Materials.
This study addresses [specific materials-science problem]. We
show that [main result], with relevance to [application or
materials domain].
The manuscript fits Materials because it reports findings on
[material type or property] rather than purely fundamental
chemistry or physics. We selected the [SECTION NAME] section
because [one-sentence justification].
The work is original, not under consideration elsewhere, and
approved by all authors.
Sincerely,
[Name]The section-naming sentence is the most important addition compared to a generic MDPI letter.
Mistakes that make these letters weak
- never naming the target section, forcing the editor to route blindly
- framing the paper as pure chemistry or pure physics with no materials angle
- describing the study topic without stating what was found about the material
- using high-impact novelty language instead of showing clear materials relevance
- submitting a paper whose center of gravity is catalysis or device physics, not the material itself
These mistakes slow triage or lead to desk rejection.
What should drive the submission decision instead
Before polishing the letter further, confirm the journal fit. Materials is broad but explicitly materials-focused -- papers whose real contribution is catalytic mechanism, device architecture, or fundamental physics will struggle regardless of letter quality. Check the journal's own author guidelines and browse recent papers in your target section to verify alignment.
Practical verdict
The strongest Materials cover letters are short, section-specific, and materials-focused. They tell the editor where to route the paper and what the materials contribution is.
So the useful takeaway is this: name your section, state the materials result, and keep the letter clean. A free Manusights scan is the fastest way to pressure-test that framing before submission.
