Despite extensive research into PU-based superhydrophobic coatings, their practical use is often limited by complex preparation methods and insufficient mechanical durability. This study introduces a simple, cost-effective method for creating superhydrophobic nanocomposite coatings with enhanced anti-icing properties. By applying a straightforward one-step thermal treatment, silica nanoparticles were hydrophobically modified. These nanoparticles, combined with PTFE powder, were incorporated into PU to form a superhydrophobic coating. The coating was analyzed using scanning electron microscopy to investigate its micro-nano-structure, atomic force microscopy and a surface profilometer to assess surface roughness, and surface free energy measurements to evaluate the effectiveness of the hydrophobic modification. The resulting coating achieved an apparent water contact angle of 152° ± 1°, representing a 116% increase compared to pure PU, and a sliding angle (SA) of 7° ± 1°. This represents a significant improvement over pure PU. It also demonstrated adequate self-cleaning and anti-icing properties. Anti-icing performance was assessed by measuring the freezing times of supercooled water droplets, demonstrating the coating's ability to delay ice formation. Additionally, the incorporation of paraffin oil was found to enhance ice inhibition. Additionally, cross-cut tape tests confirmed good adhesion. These findings confirmed that the prepared superhydrophobic nanocomposite coating shows significant potential for practical applications, offering enhanced durability, performance, and anti-icing capabilities.</p><h3>Graphical abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":619,"journal":{"name":"Journal of Coatings Technology and Research","volume":"22 5","pages":"1759 - 1773"},"PeriodicalIF":2.8,"publicationDate":"2025-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144927006","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Drying of wet polymer films in high humidity environment results in porous films that are opaque in appearance while those dried in low humidity conditions lead to transparent films without pores. The porous films show lower tensile strength compared to the transparent films. While the tensile strength of the opaque films was invariant with film thickness, the strength of the transparent film increased with decreasing film thickness.

We synthesize AEDTMP in three step reactions using ethylenediamine, formaldehyde, phosphorous acid and ammonia and characterized through Fourier transform infrared (FTIR), nuclear magnetic resonance, and ultra-performance liquid chromatography-mass spectrometry analyses. The flame-retardant finishing of cotton is done by immerse-pressing fabrics in 5% AEDTMP and 5% trimethylol melamine (TMM) binder solution with increasing treating times to realize multilayer coating on the fabrics. Vertical flame tests show an enhancement of flame retardancy and durability of the treated cotton samples as increasing the treating times. Through FTIR, thermogravimetric, cone calorimetry, scanning electron microscopy image and energy-dispersive X-ray analyses, we reveal that the P–O–C and C–O–C bonds are newly formed by reactions between the fiber, AEDTMP flame retardant and TMM binder, and the multilayer coating enhances such binding reactions. We further performed  the tests of mechanical properties, verifying that the 5-times treated sample has less effect on the comfort and air permeability of the cotton fabrics than the single-treated sample.
