Abstract Samples of a high‐purity isotactic polypropylene (iPP) were quenched from the melt so as to monitor cooling history. A continuous variation morphology and crystal structure was obtained with rate. This is discussed in relation sample thermal history evidencing that relevant samples neighborhood 90°C. In particular are essentially mesomorphic when at this temperature rates larger than 80°C/s adopted, while below few tens °C/s only α‐monocline form obtained. Densities compared...
Scaffolds suitable for tissue engineering applications like dermal reconstruction were prepared by Thermally Induced Phase Separation (TIPS) starting from a ternary solution PLLA/dioxane/water. The experimental protocol consisted of three consecutive steps, first quench the homogeneous to an appropriate demixing temperature (within metastable region), holding stage given residence time, and final low unstable region). A large variety morphologies, in terms average pore size interconnection,...
Abstract Electrospun scaffolds exhibiting high physical performances with the ability to support cell attachment and proliferation are attracting more scientific interest for tissue engineering applications. The inclusion of inorganic nanoparticles such as nanosilica nanoclay into electrospun biopolymeric matrices can meet these challenging requirements. silica clay incorporation polymeric nanofibers has been reported enhance improve mechanical properties well osteogenic scaffolds. In this...
Abstract Samples of nucleated polyamide 6 were quenched from the melt so as to monitor cooling histories. Their morphology and crystal structures discussed in relation sample thermal history; history relevant was recognized being confined interval 110 160°C. In particular, samples essentially amorphous for rates larger than 200°C/s. The γ‐crystalline form observed 70 200°C/s, whereas α crystalline structure found dominant yet lower rates. Crystallinities evaluated densities compared with...
Among the various scaffold fabrication techniques, thermally induced phase separation (TIPS) is one of most versatile methods to produce porous polymeric and it has been largely used for its capability highly interconnected scaffolds. The architecture can be closely controlled by varying process parameters, including polymer type concentration, solvent/non-solvent ratio thermal history. TIPS technique widely employed, also, scaffolds with a hierarchical pore structure composite...
Abstract The relevance of enhancement crystallisation kinetics by effect shear flow and rheology during polymer solidification to the phenomena taking place injection moulding process has been shown means simulations performed on basis Lord Williams [1, 2] model its recent extensions [3 5]. A key point simulation was criterion based a critical crystallization index; simple calorimetric rheological tests in limit zero rate, values few percent were given crystallinity value. Many experimental...
Abstract A method based on Fourier transform infrared (FTIR) transmission spectra is proposed to measure the crystallinity of isotactic polypropylene (iPP) samples. The parameters were tuned as compared with wide‐angle X‐ray scattering measurements performed test samples characterized by different values obtained solidification thin iPP films under several cooling rates in a homemade device. FTIR dichroic ratio adopted crystalline and average Hermans' orientation factors film casting....
Bio-based, biodegradable polymers can dramatically reduce the carbon dioxide released into environment by substituting fossil-derived in some applications. In this work, prototypes of trays for aquaculture applications were produced via injection molding using a polymer, Mater-Bi®. A characterization carried out calorimetric, rheological and mechanical tests revealed that polymer employed shows properties suitable production tools to be used Moreover, samples subjected biodegradation test...
A critical obstacle encountered by tissue engineering is the inability to maintain large masses of living cells upon transfer from in vitro culture conditions host vivo. Capillaries, and vascular system, are required supply essential nutrients, including oxygen, remove waste products provide a biochemical communication “highway”. The successful use tissue-engineered constructs currently limited thin or avascular tissues, such as skin cartilage, for which post-implantation neo-...
