“…This additional functionality may be diverse, and depend upon the actual application of a coated substrate. Typical examples of functional coatings are self-cleaning [8,9], easy-toclean (anti-graffiti) [10], antifouling [11], soft feel [12] and antibacterial [13][14][15]. Although various mechanisms are involved, as well as numerous applications, there is a common feature that is of particular benefit and which satisfies some users' demands.…”

Today, many objects that we come across in our daily lives, including the house in which we live and the materials we use (e.g., toothbrushes, pots and pans, refrigerators, televisions, computers, cars, furniture) all come under the "umbrella" of coated materials. Likewise, fields such as military applications -for example, vehicles, artilleries and invisible radars -and aerospace products such as aircraft, satellites and solar panels all involve the widespread use of coated materials. Clearly, the importance of coatings has increased hugely during the modern era of technology.Coating is defined as a material (usually a liquid) which is applied onto a surface and appears as either a continuous or discontinuous film after drying. However, the process of application and the resultant dry film is also regarded as coating [1]. Drying of the liquid coating is mostly carried out by evaporative means or curing (cross-linking) by oxidative, thermal or ultraviolet light and other available methods. Paint can be defined as a dispersion that consists of binder(s), volatile components, pigments and additives (catalyst, driers, f low modifiers) [2]. The binder (polymer or resin) is the component that forms the continuous film, adheres to the substrate, and holds the pigments and fillers in the solid film. The volatile component is the solvent that is used for adjusting the viscosity of the formulation for easy application. Depending on their compositions, paints can be divided into three groups: solvent-borne, water-borne and solvent-free (100% solid). Solvent-borne paints consist of resin, additives and pigments that are dissolved or dispersed in organic solvents. Similarly, in water-borne paints the ingredients are dispersed in water. In solvent-free compositions, the paints do not contain any solvent or water and the ingredients are dispersed directly in the resin.The properties of coating films are determined by the types of binders, pigments and miscellaneous additives used in the formulation. Moreover, types of substrates, substrate pretreatments, application methods and conditions of film formation

“…However, plasma treatment techniques (Keil et al 1998;Dahl et al 1999;Seidel et al 1999;Munzert et al 2003;Lee et al 2004;Muir et al 2006) and deposition of carbonyl silica layers (Zajickova et al 1998(Zajickova et al , 2001; Benitez et al 2000; Kuhr et al 2003;Barrell et al 2004;Kressig et al 2004) have been used to achieve surface wettability as well as hardening. Therefore, the plasma process has been adopted and optimized for achieving increased surface wettability and hardness, as well as for the deposition of ARC on the treated plastic surface.…”

“…So, a plasticlike carbonyl silica film is supposed to adhere well to the plastic substrate due to the presence of carbonyl groups on both sides. Further, carbonyl silica films are known to provide a hard surface (Zajickova et al 1998(Zajickova et al , 2001; Benitez et al 2000; Kuhr et al 2003;Barrell et al 2004;Kressig et al 2004). A thick carbonyl silica film also acts as sponge to absorb any mechanical shock due to stress effects, etc.…”

“…A thick carbonyl silica film also acts as sponge to absorb any mechanical shock due to stress effects, etc. (Kuhr et al 2003;Kressig et al 2004). As silica contains oxygen and silicon, subsequently deposited oxide films should adhere better to the carbonyl silica film.…”

“…Ion implantation techniques (Bhattacharya 1998;Guzman et al 1998) and ion beam sputtering (Sarto et al 1999) have also been used to increase surface hardness and abrasion resistance. However, exposure to plasma (Keil et al 1998;Dahl et al 1999;Seidel et al 1999;Martinu and Poitras 2000;Munzert et al 2003;Lee et al 2004;Muir et al 2006) and plasma polymerization deposition of a carbonyl silica layer (Zajickova et al 1998(Zajickova et al , 2001; Benitez et al 2000; Kuhr et al 2003;Barrell et al 2004;Kressig et al 2004) offer techniques for achieving surface wettability as well as hardness. These processes, as well as the deposition of the optical coating like ARC itself, can all be carried out by plasma polymerization processes in the same deposition system, by varying the deposition process parameters (the gas and precursor introduced into the chamber, their flow rates, applied power level, bias voltage applied, and so on) at each step.…”

Antireflection coatings on plastics deposited by plasma polymerization process

et al. 2008

Abstract. Antireflection coatings (ARCs) are deposited on the surfaces of optical elements like spectacle lenses to increase light transmission and improve their performance. In the ophthalmic industry, plastic lenses are rapidly displacing glass lenses due to several advantageous features. However, the deposition of ARCs on plastic lenses is a challenging task, because the plastic surface needs treatment for adhesion improvement and surface hardening before depositing the ARC. This surface treatment is usually done in a multi-stage processexposure to energetic radiations, followed by deposition of a carbonyl hard coating by spin or dip coating processes, UV curing, etc. However, this treatment can also be done by plasma processes. Moreover, the plasma polymerization process allows deposition of optical films at room temperature, essential for plastics. The energetic ions in plasma processes provide similar effects as in ion assisted physical deposition processes to produce hard coatings, without requiring sophisticated ion sources. The plasma polymerization process is more economical than ion-assisted physical vapour deposition processes as regards equipment and source materials and is more cost-effective, enabling the surface treatment and deposition of the ARC in the same deposition system in a single run by varying the system parameters at each step. Since published results of the plasma polymerization processes developed abroad are rather sketchy and the techniques are mostly veiled in commercial secrecy, innovative and indigenous plasma-based techniques have been developed in this work for depositing the complete ARCs on plastic substrates.
