Abstract

A new type of superhydrophobic borneol-based polymeric coating has been prepared. The chemical composition of the polymer particles was analyzed by Fourier transform infrared spectroscopy and X-ray photoelectron spectroscopy, which showed that the polymer did not contain fluorine, which can effectively avoid the cytotoxic risk of fluorine. By dynamic light scattering, scanning electron microscopy, and static contact angle measurement, the contact angle of the prepared coating gradually increased with increasing diameter of the polymer particles, and a superhydrophobic coating surface was finally obtained. Interestingly, after dissolving the superhydrophobic sample with tetrahydrofuran and making it a normal hydrophobic sample, the antiadhesion performance for E. coli was greatly reduced, and it could not effectively prevent E. coli adhesion. In addition, a long-term antiadhesion study of bacteria was performed. The superhydrophobic borneol-based polymer coating showed long-term resistance to E. coli adhesion. Therefore, the excellent antibacterial properties and cell compatibility mean that this series of polymer materials has great potential in the field of biomedicine.

新型龙脑基无氟超疏水抗菌聚合物涂料。

制备了一种新型的超疏水冰片基聚合物涂料。通过傅立叶变换红外光谱和X射线光电子能谱分析了聚合物颗粒的化学成分，表明聚合物不含氟，可以有效避免氟的细胞毒性风险。通过动态光散射、扫描电子显微镜和静态接触角测量，所制备的涂层的接触角随着聚合物颗粒直径的增加而逐渐增大，最终获得了超疏水涂层表面。有趣的是，用四氢呋喃溶解超疏水性样品并使其成为正常疏水性样品后，对大肠杆菌的抗粘附性能大大降低，并且不能有效防止大肠杆菌粘附。此外，还对细菌进行了长期的抗粘附研究。基于冰片的超疏水聚合物涂层显示出对大肠杆菌粘附的长期抗性。因此，该系列聚合物材料具有优异的抗菌性能和细胞相容性，在生物医学领域具有巨大的潜力。

期刊介绍： Designed Monomers and Polymers ( DMP) publishes prompt peer-reviewed papers and short topical reviews on all areas of macromolecular design and applications. Emphasis is placed on the preparations of new monomers, including characterization and applications. Experiments should be presented in sufficient detail (including specific observations, precautionary notes, use of new materials, techniques, and their possible problems) that they could be reproduced by any researcher wishing to repeat the work. The journal also includes macromolecular design of polymeric materials (such as polymeric biomaterials, biomedical polymers, etc.) with medical applications. DMP provides an interface between organic and polymer chemistries and aims to bridge the gap between monomer synthesis and the design of new polymers. Submssions are invited in the areas including, but not limited to: -macromolecular science, initiators, macroinitiators for macromolecular design -kinetics, mechanism and modelling aspects of polymerization -new methods of synthesis of known monomers -new monomers (must show evidence for polymerization, e.g. polycondensation, sequential combination, oxidative coupling, radiation, plasma polymerization) -functional prepolymers of various architectures such as hyperbranched polymers, telechelic polymers, macromonomers, or dendrimers -new polymeric materials with biomedical applications
