Typically, reversible thermogelling properties of amphiphilic block copolymers are attributed to the use of a temperature-sensitive block, which enables temperature-dependent reversible formation of a micellar network. The nature of the micellar network is contingent upon the nanostructures formed by the underlying amphiphilic block copolymer, which in turn depends on the polymers' composition and structure. Thus, micellar gel networks of BAB-type block copolymers, where A and B signify hydrophilic and hydrophobic/temperature-sensitive blocks, respectively, are generally achieved by bridging of flower-like micelles. AB and ABA polymers, in contrast, typically undergo gelation due to the packing of regular spherical micelles, as is the case with Pluronics F127. This ABA type triblock copolymer is arguably the most widely used block copolymer with thermogelling properties in the biomedical field. Being composed of hydrophilic polyethylene glycol (PEG) outer blocks and a thermosensitive polypropylene glycol (PPG) central block, it belongs to the class of Pluronic amphiphiles, also known as poloxamers. While most of the Pluronic members do not exhibit reversible thermogelling properties, they do show amphiphilic behaviour, i.e., aggregation in aqueous solutions above the critical micellar temperature and concentration. Interestingly, for some of these amphiphiles, a progressive transition from spherical micelles towards worm-like micelles upon temperature increase has been reported, mostly in the presence of an electrolyte. This transition results from an enlargement of the hydrophobic core radius, following the packing parameter criterion first introduced by Israelachvili for conventional surfactants . Of note, the reversible transition in Pluronic self-assembly is characterized by a viscosity increase, which can eventually lead to gel-like properties. However, due to the narrow phase region of worm-like aggregates, which requires maintaining a delicate balance of hydrophilic and hydrophobic volume fractions, reports on the thermogelation based on Pluronic and other amphiphilic block copolymer worms are relatively scarce. One of the rare example of thermoreversible gelation based on worm-like micelles (worm-gels) is given by a unique class of shape-shifting diblock copolymers introduced by Armes and coworkers. The thermoreversible behaviour of these systems is attributed to the use of weakly hydrophobic polymer blocks based on hydroxylfunctional (meth)acrylates , rather than classical thermoresponsive polymer blocks. These mildly hydrophobic blocks are subject to temperature induced subtle alterations in the degree of partial hydration which enable transitions in polymer selfassembly. The first introduced system of this class comprised a hydrophilic poly(glycerol monomethacrylate) (pGMA) and a more hydrophobic poly(2-hydroxypropyl methacrylate) (pHPMA) block. The pGMA-b-pHPMA diblock copolymer was shown to undergo a reversible transition from spherical to worm-like micelles upon heating above 21 °C, resulting in the formation of a soft freestanding physical hydrogel due to interworm entanglements. Variation of the system using alternative hydrophilic blocks, such as PEG or poly(2-(methacryloyloxy) ethyl phosphorylcholine) (PMPC) , resulted in similar behaviour. However, with the focus being on accessible morphologies, detailed systematic studies of the influence of hydrophilic moieties on gel properties have not been performed.
