Ultraviolet and heat-curable polyurethane acrylate prepolymers were synthesized from 4,4’-diphenyl methane diisocyanate, polyethylene adipate diol, polyhexamethylene carbonate diol, polycaprolactone diol and 1,6hexamethylene diamine , acrylic acid. Effects of nature of the soft segments on the physical properties were investigated. It was found that the thermal stability increased from polycarb...

Objective(s): Fabrication of scaffolds with improved mechanical properties and favorable cellular compatibility is crucial for many tissue engineering applications. This study was aimed to improve mechanical and biological properties of polycaprolactone (PCL), which is a common biocompatible and biodegradable synthetic polymer in tissue engineering. Nanofibrillated chitosan (NC) was used as a n...

The following manuscript presents the first attempt to fabricate and characterise electrospun polycaprolactone/poly(succinimide) composite meshes. While each material has its own advantages, a mesh could provide further options in wide diverse application spectrum of fibrous membranes. Polycaprolactone is well-known polymer with excellent mechanical properties resistance against most chemicals....

We report a facile and general strategy for enhancing the photostability of organic fluorophores for bioimaging applications. As a proof of concept, bright and robust fluorescence was observed in solid states of a well-defined synthetic polymer polycaprolactone consisting of di(thiophene-2-yl)-diketopyrrolopyrrole covalently linked in the middle of the polymer chain as a biocompatible and biore...

Ordinarily, the electrospinning process generates one-dimensional fibers which assemble into nonwoven membrane structures due to instabilities in the fluid jet. In this paper, an electrospinning procedure is developed that utilizes patterned collectors to produce aligned membranes with designed topological structures. The template-assisted electrospinning approach is demonstrated using polycapr...

Dense CO2 can be used as an environmentally-benign polymer processing medium because of its liquid-like densities and gas-like mass transfer properties.In this work, polymer bio-blends of polycarbonate (PC), a biocompatible polymer, and polycaprolactone (PCL), a biodegradable polymer were prepared. Dense CO2 was used as a reaction medium for the melt-phase PC polymerization in the presence of d...

Glycopolymers with mannose units were readily prepared by click chemistry of an azido mannopyranoside derivative and a poly(propargyl acrylate-co-N-vinyl pyrrolidone). These glycopolymers were used as polymer surfactants, in order to obtain glycosylated polycaprolactone nanoparticles. Optimum stabilization for long time storage was achieved by using a mixture of glycopolymers and the non-ionic ...
