“…4. The results indicate that the hybrid films (PBZ, PBS and PBST [1][2][3][4] begin to decompose at 400°C and above are typically exhibit 10 % weight losses between 353 and 481°C as presented in Table 3. An incorporation of SiO 2 and TiO 2 causes an increase in initial thermal decomposition temperatures (T d 1 ).…”

In the present work, silica and titania reinforced polybenzoxazine (PBZ-SiO 2 -TiO 2 ) hybrid nanomaterial possessing high surface free energy have been developed using dimethylol-functional benzoxazine monomer (4HBA-BZ), tetraethoxysilane (TEOS), 3-(isocyanatopropyl)triethoxysilane (ICPTS), titaniumisopropoxide (TIPO) through an in situ sol-gel process. Data obtained from the contact angle measurement indicate that the hybrid materials are hydrophilic in nature and possess a high surface free energy. For example, hybrid PBZ obtained from 1:1:0.6:0.4 (m:m:w:w) ratio of 4HBA-BZ:ICPTS:TEOS:TIPO (PB ST 4 ) exhibit a high surface free energy of 38.2 mJm -2 which is higher than that of neat polybenzoxazine (29.5 mJm -2 ). Further data resulted from thermal studies indicate that the hybrid PBZ possess higher values of T g , thermal stability and char yield than those of neat PBZ.

“…Furthermore, the processing depths in which modification can occur are small and could have implications with regards to the robustness of the developed surface. Cho et al [169] employed ion assisted reactions (IAR) to modify the surface of polymeric materials to manipulate the wettability characteristics, enhancing their hydrophilic nature. In addition, Aubry et al [170], used a focused ion beam (FIB) to generate surface topographies that had a high enough resolution for applications in diffractive optical elements (DOEs).…”

On account of the recent increase in importance of biological and microbiological adhesion in industries such as healthcare and food manufacturing many researchers are now turning to the study of materials, wettability and adhesion to develop the technology within these industries further. This is highly significant as the stem cell industry alone, for example, is currently worth £3.5 million in the United Kingdom (UK) alone. This paper reviews the current state-of-the-art techniques used for surface treatment with regards to modulating biological adhesion including laser surface treatment, plasma treatment, micro/nano printing and lithography, specifically highlighting areas of interest for further consideration by the scientific community. What is more, this review discusses the advantages and disadvantages of the current techniques enabling the assessment of the most attractive means for modulating biological adhesion, taking in to account cost effectiveness, complexity of equipment and capabilities for processing and analysis.

“…The surface modification of stainless steel prior to application is a critical process and is important to surface coating. Many investigations have been conducted on the surface modification of a wide variety of organic materials, inorganic materials, and metals [3][4][5][6][7][8][9][10]. Plasma treatment is one of the most commonly used surface modification methods due to its favorable wettability, permeability, conductivity, adhesion, and biocompatibility properties [3].…”
