To achieve appropriate monomer vapor pressure, PFDA was heated to 60 °C or 50 °C (for S1-S3, F1-F2, H1-H2), HEMA was heated to 50 °C, and EGDA was heated to 35 °C. TBPO was kept at room temperature of 25 °C and

• chemical vapor deposition (iCVD) were investigated. PFDA polymers are known for their interesting crystalline aggregation into a lamellar structure that induces super-hydrophobicity and oleophobicity. Nevertheless, when considering applications which involve chemical, mechanical and thermal stresses, it is

• important to know the limits under which the crystalline aggregation and the resulting polymer properties are stable. For this, chemical, morphological and structural properties upon multiple heating/cooling cycles were investigated both for linear PFDA polymers and for differently strong cross-linked
