“…To allow sole focus on the physical properties arising as a consequence of the hard segment, end-groups were selected with predictable contributions to the self-assembly process, thus allowing comparison to analogues derived from MDI. 26,29,46,[57][58][59][60] Termination of the prepolymer 7 was successfully achieved by addition of either derivatives containing morpholine or dibutylamine motifs (8-11) with amino or hydroxyl functionalities, respectively ( Table 1).…”

“…11,12 A recent development in PU chemistries has been the investigation of supramolecular polyurethane (SPU) networks [13][14][15][16][17][18] which are able to self-assemble through weak non-covalent interactions. [19][20][21][22][23][24][25][26][27] These materials are attractive on account of their thermo-reversible characteristics. [28][29][30][31][32] Gooch and co-workers have reported 33 Feula et al 36 have developed a well-defined hydrogen bonded SPU with a low dissociation temperature which permits healing at physiological temperatures.…”

Abstract:In this work, the production of continuous submicron diameter saccharide fibres is shown to be possible using the electrospinning process. The mechanism for the formation of electrospun polymer fibres is usually attributed to the physical entanglement of long molecular chains. The ability to electrospin continuous fibre from a low molecular weight saccharides was an unexpected phenomenon. The formation of sub-micron diameter "sugar syrup" fibres was observed in situ using highspeed video. The trajectory of the electrospun saccharide fibre was observed to follow that typical of electrospun polymers. Based on initial food grade glucose syrup tests, various solutions based on combinations of syrup components, i.e. mono-, di-and tri-saccharides, were investigated to map out materials and electrospinning conditions that would lead to the formation of fibre. This work demonstrated that sucrose exhibits the highest propensity for fibre formation during electrospinning amongst the various types of saccharide solutions studied. The possibility of electrospinning low molecular weight saccharides into sub-micron fibres has implications for the electrospinability of supramolecular polymers and other biomaterials.

“…As a method for producing nano‐ and micro‐scale fibers, intensive research effort has been focused on using electrospinning technique during the last few decades. So far, a wide range of polymers have been spun to be used for different purposes; including commonly polymers such as poly acrylonitrile, poly amide, and poly ethylene terephthalate, as well as specific polymers such as biocompatible polymers, conductive polymers and supramolecular compounds . Generally, the trial and error is the method widely addressed by many researchers in order to get the optimal conditions for fabricating the fine fibers with controlled thickness.…”

Formation of specific structures on poly-ɛ-caprolactone (PCL) and poly lactide-co-glycolide (PLGA) based electrospun mats is rationalized and the effect of interactive parameters; high voltage and flow rate on unique surface topography is evaluated. By increasing the collecting time in electrospinning process and enhancing fiber to fiber repulsion, surface characteristics of mats changes from nano- to micro-topography. In this study surface topography of the fabricated mats based on PCL and PLGA were assessed using AFM and SEM techniques to display the distinct phenomenon occurs on collected random fibers. In this research the rationale behind the formation of bump and flower like structures on fibrous mats was discussed. Because of great potential application of the fabricated substrates in the fields of medical purposes, cell-matrix interaction was evaluated and in vitro biological test with human dermal fibroblast and mouse L929 fibroblast cells was performed to study the cell responses to different roughness of nano-fibers collected at different time intervals. Our results show that after 7 days, cell proliferation is improved on PCL collected at 40 min in the case of human fibroblast cells and on PCL collected in 70 min in the case of L929 mouse fibroblast cells.
