“…Silanized glass slides showed distinct bands corresponding to the primary amine of APTES between 3400 and 3250 cm −1 , 39 while the bands at 2960 and 2870 cm −1 correspond to CH 2 and CH 3 groups of APTES ethoxy fragments. 40 The poly(B5AMA)grafted glass surface showed distinct absorption peaks at 1650 cm −1 assigned to the CO stretching of amide bonds, and the strong broad absorption from 3550 to 3200 cm −1 was attributed to the hydroxyl groups present in the pendant chains of poly(B5AMA). 41 The samples prepared were identified as a function of APTES concentration and of poly(B5AMA) sizes grafted onto the glass slides; for example, 1.25% APTES-modified glass treated with poly(B5AMA) 22 was indicated as 1.25Am-p(B5AMA) 22 .…”

“…The carboxyl end group-containing poly(B5AMA) were then immobilized on primary amine-functionalized glass surfaces using HBTU as a coupling agent, and the functionalization process was investigated by FTIR spectroscopy (Supporting Information, Figure S7b). Silanized glass slides showed distinct bands corresponding to the primary amine of APTES between 3400 and 3250 cm –1 , while the bands at 2960 and 2870 cm –1 correspond to CH 2 and CH 3 groups of APTES ethoxy fragments . The poly(B5AMA)-grafted glass surface showed distinct absorption peaks at 1650 cm –1 assigned to the CO stretching of amide bonds, and the strong broad absorption from 3550 to 3200 cm –1 was attributed to the hydroxyl groups present in the pendant chains of poly(B5AMA) .…”

This study reports the synthesis of well-defined polymers of vitamin B5 analogous methacrylamide (poly(B5AMA)) using the reversible addition fragmentation chain transfer polymerization method. The prepared telechelic poly(B5AMA) with a predicted molecular weight and narrow polydispersities are grafted onto silanized glass surfaces using a “grafting to” approach. The polymer-treated samples are characterized for the water contact angle and surface roughness properties, as a function of polymer size and density of the polymers grafted onto the glass slides. The antifouling behavior of poly(B5AMA)-grafted glass slides is then studied and compared with that of PEGylated glass slides, upon treatment with a variety of proteins and bacteria. The functionalized surfaces exhibit remarkable antifouling properties that are found to be dependent on both the density and the molecular weight of the grafted polymers.

Advanced materials are among the prime drivers for technological revolutions and transformation in quality of lives. Over time, several modification techniques have emerged enabling development of novel materials with extraordinary features. The present review aims to introduce various promising chemical and physical surface modification techniques instrumental for tailoring the characteristics of thin films and membranes. Meticulous discussions are provided over chemical vapor deposition (CVD) techniques evolved for addressing the demands for materials with desired functionalities. Also, essential criteria for the selection of substrates, modifying and precursor materials for an effective CVD modification are elaborated. Investigations are extended to unraveling the role of various process parameters on the quality and properties of deposition. Special attention is paid to the significance and performance of CVD‐based membranes and thin films for industrial applications ranging from desalination and water treatment to energy and environment, biomedical and life science as well as packaging. The goal has been to establish a scientific platform for a timely tracking of the prevailing trends in exploitation of CVD techniques and highlighting the unexplored opportunities. This also helps in identification of the scientific and technical gaps and setting directions for further progress in the fields of thin films and membranes.

“…We argue that the proposed method can also be applied to other NP where the APTES coating is used as a surfacebinding agent, for instance, for NPs made of Ag, 52,53 SiO 2 , 54 TiO 2 , 55,56 Fe 2 O 3 56 and Y-zeolites. 57 Moreover, one can expect that NPs with different sizes will require a different UV irradiation time for achieving similar surface coverages.…”

Ultraviolet Deactivation of Silane-Functionalized Surfaces: A Scalable Approach for Patterned Nanoparticle Assembly

Developing optoelectronic devices, biological or chemical sensors, displays, and other devices based on nanoparticles (NPs) requires designing tailored NP assemblies on solid substrates, and often with a given surface positioning. In our study, we discuss a new soft-lithographic method for patterning an organic layer, which is capable of binding gold nanoparticles (AuNPs) to the surface. AuNPs with a citrate shell were 17 nm in diameter and prepared by the Turkevich protocol. Our method is based on controlling the binding capability of (3-aminopropyl)trimethoxysilane (APTES)-coated surface by deactivating the −NH2 terminal groups of APTES under the action of UV-generated ozone in air. We show that partial and complete deactivation can be achieved depending on the atmosphere and exposure time. Using a shadow mask during irradiation, we furthermore show that our method can be applied for creating micron-scale arrays of NPs on APTES-coated substrates with a spatial resolution down to ∼1.5 μm, currently limited by the properties of the mask.
