Nanoscale deposition of chemically functionalised films via plasma polymerisation

Plasma polymerisation is a technologically important surface engineering process capable of depositing ultra-thin functionalised films for a variety of purposes. It has many advantages over other surface engineering processes, including that it is completely dry, can be used for complex geometries, and the physico-chemical properties of the film can be tailored through judicious choice of processing conditions. Despite this, the mechanisms of film growth are largely unknown, and current models are based on purely chemical arguments. Consideration of some basic plasma physics shows that some species can arrive at surfaces with energies greater than 1000 kJ mol 21 (.10 eV), and thus open a range of surface reactions that have not been considered previously. This review aims to close the gap between the physics and chemistry of reactive plasma systems.

“…These polymer films can be highly functionalised and have been applied in a diverse range of applications, but especially in the field of biomaterials . In general, there are two types of reactor system used in laboratories undertaking this type of research: glass‐wall reactor systems with external electrodes (which may be in the form of copper bands or external coils as in so‐called ‘inductive’ radiofrequency plasma sources but which are nevertheless capacitively coupled systems when operated at low powers) and stainless steel or glass‐walled systems with internal electrodes (which are capacitively coupled).…”

Plasma processing is widely used to provide novel surface modifications to materials for a variety of applications. Typically, the systems used to carry out these modifications are poorly characterised. Here we describe the basics of a global model for a capacitively coupled asymmetric parallel plate radiofrequency plasma system routinely used to produce plasma polymers. An analytical global model was developed for argon, for which cross-sections are known, at a constant pressure of 1 Pa, and includes an electrical model and a power balance. The main parameters of interest were ion flux and self-bias voltages. The argon modelling results were then compared to experimental results for a range of operating gases (argon, oxygen, amines, acids, alcohols, ethers, siloxanes) including both saturated and unsaturated compounds with molecular weights ranging from 40 to 162 g Á mol À1 , for different inter-electrode separations and from 2 to 50 W using an Impedans OctIV probe. Importantly, it is shown that the RF power transfer efficiency is dependent on the gas. The results show that the argon model results can be used to predict the plasma parameters for other gases when the RF power transfer efficiency is taken into account.

[48] Pulsed plasma-deposited poly(hexyl acrylate) shows loss of the acrylate carbon-carbon double bond infrared absorbance features, thereby confirming that polymerization took place. [35] Atomic force microscopy (AFM) roughness measurements showed that the pulsed plasma poly(hexyl acrylate) coating surface is not significantly more rough compared with uncoated silicon wafer substrate (Roughness RMS ¼ 1.99 nm vs 0.68 nm, respectively, for 10 μm scan size)-which is typical of low-duty cycle pulsed plasma-deposited polymer nanocoatings, as shown in Figure 1.…”

Nature‐Inspired Substrate‐Independent Omniphobic and Antimicrobial Slippery Surfaces

Inspired by the carnivorous Nepenthes pitcher plant, a range of highly liquid repellent lubricant‐infused surfaces has been devised (low water droplet contact angle hysteresis and sliding angle values). This entails matching functional pulsed plasma polymer nanolayers with appropriate slippery lubricants. A molecular‐level structure–behavior relationship is developed, highlighting the importance of favorable aromatic–aliphatic intermolecular interactions between the coating and lubricant. Fluorinated lubricant‐infused pulsed plasma polymer nanocoatings resist wetting by liquids, spanning a wide range of surface tensions (including pentane, motor oil, and water, i.e., omniphobicity). In the case of natural antimicrobial compound‐infused functional plasma polymer surfaces (e.g., the essential oil cinnamaldehyde), multifunctional performance is attained combining high liquid repellency (self‐cleaning) with simultaneous strong antibacterial activity against both Gram‐positive Staphylococcus aureus and Gram‐negative Escherichia coli (log10 reduction > 7). In addition, these lubricant‐infused functional pulsed plasma polymer surfaces easily repel a variety of everyday liquids (including foodstuffs such as tomato ketchup and honey).
