Polyamide 66 (PA66), being an engineering polymer with excellent physio-mechanical properties, exhibits immense possibilities to be developed as a multifunctional textile substrate. In this work, multi-functional polyamide 66 (PA66) textiles equipped with enhanced electro-conductive, hydrophilic and flame-retardant properties were developed via <i>in situ</i> polymerization of pyrrole monomer onto the PA66 fabric surfaces. Meanwhile, various formulations comprised of phytic acid (PA), chitosan (CS), graphene oxide (GO) and Na-metaborate (B) along with the pyrrole also experimented with a goal to study the contribution of each compound onto the desired properties and finally, to come up with a suitable formulation. Among these formulations, only pyrrole containing formulation (i.e., PA66-PPy) demonstrated a significant improvement in all three desired functionalities, namely a noteworthy escalation in electrical conductivity (i.e., about a 43 times increase compared to the pure PA66), a semi-hydrophilic surface (i.e., water contact angle value was lowered from 124.3– 49.9°) and a substantial reduction in the peak heat release rate by 45%. Meanwhile, the formulation comprising both the pyrrole and phytic acid made the polyamide surface a super-hydrophilic one, whereas other formulations exhibited potential efficacy in attaining better flame retardancy, especially in terms of limiting oxygen index (LOI) values, vertical flame test data and char yield%.</p><h3>Graphical abstract</h3>\u0000 <figure><div><div><div><picture><source><img></source></picture></div></div></div></figure>\u0000 </div>","PeriodicalId":48804,"journal":{"name":"Journal of Coatings Technology and Research","volume":"20 4","pages":"1223 - 1234"},"PeriodicalIF":2.3,"publicationDate":"2023-02-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s11998-022-00738-3.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"4116894","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

By means of electrospraying, it is possible to create uniform and fine droplets that attract to the substrate without being blown away by the electric field formed by the nozzle and the substrate. The uniformity of the coated layer is rarely affected by a fluid drying process (such as Marangoni flow on substrates) as the size of droplets can reach micron/nano-levels and the solvents in the droplets can evaporate quickly. Therefore, the electrospray process is often referred to as ‘dry deposition.’ However, when an electrospray system with multinozzles is considered for the faster process of producing large substrates, the drying process may be completely different than for a single-nozzle system. In addition, crosstalk and nonuniform spray volume from each nozzle can pose an additional problem that needs to be addressed.

Initially, the nanocoatings were prepared by depositing DA, PEI, and SiO₂ on the dopamine (DA)-modified 304 stainless steel (SS) surface, and finally, the DA/PEI/SiO₂/AMPs composite coatings were prepared by grafting antimicrobial peptides (AMPs). The surfaces of SS before and after modification were characterized by Fourier transform infrared spectrometer (FTIR), X-ray photoelectron spectrometer (XPS), field emission scanning electron microscopy (SEM), contact angle measurement, and 3D optical profilometer.

The results revealed that the cells cultured on the modified surface still maintained a good adhesion morphology, demonstrating the superior cytocompatibility of the composite coating.

The antibacterial efficiency of SS-DA/PEI/SiO₂ surfaces before and after AMPs modification reached 78.39 and 95.90%, and anti-biofilm efficiency of AMPs modified surface achieved 72.87% corresponding to 44.19% of SS-DA/PEI/SiO₂.

However, the complexity of the spray pattern of the ESRB and the automobile surface geometric makes the spray process planning a more challenging problem. This paper aims to provide a new parameterized model of the ESRB to facilitate the thickness calculation and trajectory planning in the off-line painting programming. Firstly, according to the distribution characteristics of paint particles and the force analysis of adhesion process, a new static deposition rate model—offset asymmetric Gaussian model is proposed on the plane. The parameters in the new model have intuitive practical significance and can fully reflect the characteristics of ESRB coating deposition rate. Then based on the analysis of the relationship between the static model and uniform linear spraying deposition, the static model is established by measuring the layer data of corresponding uniform linear spraying. In order to further simulate the paint thickness on curved surfaces, the projection model with variable spraying distance and deposition point normal deflection is also deduced. Finally, a parameterized static model and sampling points library are established which provide efficient and accurate prediction of static deposition result, and is more suitable for off-line programming. Three different groups of simulation proved that the proposed static deposition rate model has high calculation accuracy for different working conditions and fast simulation speed for different spraying parameters.</p></div>","PeriodicalId":48804,"journal":{"name":"Journal of Coatings Technology and Research","volume":"20 3","pages":"1019 - 1037"},"PeriodicalIF":2.3,"publicationDate":"2023-01-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s11998-022-00721-y.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"4122583","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For this aim, first, the synthesis of a four-component reference alkyd resin having an oil content of 50% was synthesized by using tall oil fatty acid (TOFA), trimethylolpropane (TMP), phthalic anhydride (PA), and dipropylene glycol (DPG). The PET-based alkyd resins were also synthesized using different amounts and types of purified and fractionated depolymerization intermediates (water-insoluble fraction, WIF, and water-soluble and crystallizable fraction, WSCF) under the same reaction conditions. For the synthesis of PET-based alkyd resins, the depolymerization intermediates were used partially or completely instead of dibasic acid and/or diol components in alkyd resin formulations. In order to determine the optimum modification ratio for urethane-modified alkyd resin synthesis, the reference alkyd resin was reacted with toluene diisocyanate (TDI) at different molar ratios (NCO/OH: 1/1, 1/2, and 1/3), and the optimum NCO/OH ratio was determined as 1/1, according to the surface coating properties. And, then, all PET-based urethane-modified alkyd resins were prepared by the modification reactions of the PET-based alkyd resins with TDI at an optimum ratio. At the end of the study, it was observed that the use of waste PET intermediates (WIF or WSCF) did not cause any negative effects on physical/chemical surface coating and thermal properties; on the contrary, some properties were obtained as superior than that of the reference resin. In conclusion, it seems possible to use PET-based urethane-modified alkyd resin could be used as a cheap, environmentally friendly, and relatively economic binder component in synthetic paint formulations. In the synthesis of urethane-modified alkyd resin, using a certain amount of waste PET intermediate instead of dibasic acid and/or diol component will reduce raw material costs and also benefit the environment by re-evaluation of recycled PET. Thus, it could be both possible to recycle of post-consumer PET bottles, which are a valuable waste, and to provide cheap raw materials without compromising its features for paint formulations.
