“…APTES coated AAO surface also has been used as the surface attached initiator for grafting polymer brushes on membrane surfaces. For example grafting of poly(γ-benzyl-Lglutame) PBLG [41] and PNIPAM (poly(N-isopropylacrylamide) [42] via surface initiated polymerization. This work determines that, the density of the polymers can be controlled by controlling the density of initiator.…”

“…This result suggests that the length of the polymer in the porous network can be used to control the size of surface pores, surface roughness and the interfacial energy. Changes in initiators have been described as potentially useful in ATRP applications [42,53]. For example, Li et al [42] employed 2-boromoisobutyryl bromide (BIBB) on the membrane surface to graft PNIPAM using ATRP method.…”

Nanoporous materials with straight channels have attracted considerable interest due to their unique physical properties and many potential applications such as separation, sensing, biomedical and electronics. For the last few decades, nanoporous alumina or anodic aluminium oxide (AAO) membrane is gaining attention due to its broad applicability in various applications. The unique properties of AAO membrane coupled with tunable surface modification and properties is playing an increasingly important platform in a diverse range of applications such as separation, energy storage, drug delivery and template synthesis, as well as biosensing, tissue engineering and catalytic studies. This chapter aims to introduce the recent advances and challenges for surface manipulation of AAO following the 'soft' and 'hard' modification strategies. The functions of these modified nanostructures materials and latest important applications are evaluated with respect to improved performance and possible implications of those strategies for the future trends of surface engineering are discussed.

“…Various successive approaches such as surface modifications [4,5], feed water conditioning [6], backwashing [7] and chemical cleaning [8] have been researched to tackle the fouling phenomenon that invariably leads to membrane deterioration. Proper combination of these approaches has been successful in mitigating the fouling process to a modest extent.…”

“…Different innovative physical and chemical surface modification techniques have been introduced by various researchers in the field of polymers [9]. These techniques include ultraviolet (UV) [9], plasma [4,9], chemical [5,9] induced free radical graft polymerization, atom transfer radical polymerization (ATRP) [5,10] and surface irradiation [11]. These techniques are also frequently used to functionalize polymeric membrane surfaces.…”
