Hydrophilicity, pores with interconnected structures, and degradability are important properties of tissue engineering scaffolds. Polycaprolactone (PCL), dicalcium phosphate dihydrate (DCPD) and/or calcium silicates (CaSi) have been used to prepare highly porous scaffolds by thermally induced phase separation technique (TIPS). Abstract Polycaprolactone (PCL)/starch and PCL/starch/pine‐leaf composites, ... A universal testing machine was used to investigate the tensile properties of the composites and the water absorption properties of the composites were also investigated. The aim of this study is an examination of the influence of different processing additives on the resistance of the polycaprolactone film to different water environments. The dispersion of filler in a polymer matrix has a great effect on the structural-property relationship of the formed composite. Scanning electron microscope was used to investigate the morphology of the composites. The degradability after introducing spirulina extract (SP-E) to polycaprolactone (PCL) via particulate leaching to obtain SP-E/PCL scaffolds was characterized on the basis of their porosity, hydrophilicity, water absorption capacity, and degradability. The water absorption capacity of the NaOH-treated PCL/HA dual-leached scaffold increased greatly, confirming that the hydrophilicity of the scaffold was improved by NaOH treatment. The values of the liquid absorption and water contact angle were measured for the electrospun mats, with the F-capped PCL consistently showing absorption values up to three times higher than those of PCL samples capped with the other two alcohols, as well as increased hydrophobicity. In this context, surface modification of reduced graphene oxide (RGO) by hyperbranched polyester (PES) has been performed to facilitate its incorporation in polycaprolactone (PCL) matrix by melt blending technique.

The blending of the PHB and PHBV in PCL scaffolds results in decreased porosities of the scaffolds, and the water absorption capacities of the scaffolds also decrease. Hi, I am doing a project with polycaprolactone and I'm just wondering what fluid will dissolve in and what fluid will it be completely inert to. contribute to the absorption process 2). Water absorption was calculated by weighing the samples before and after soaking in distilled water for 12 h. The percentage increase in water absorption was calculated as (%)= (W 12 h − W o)/W o × 100, where W 12 h was the weight of the sample … Five specimens from each blend formulation were dried in an oven for 72 h at 40 °C, and weighed to the nearest 0.001 g. These samples were immersed in deionized water at room temperature. References to a … The water absorption of the prepared PU networks was investigated by their immersion in distilled water for 48 h at room temperature and the obtained results are given in Fig. The compressive modulus of the PCL/HA dual-leached scaffold was greatly increased by the addition of HA particles. Kate L Harrison. The water absorption Water Absorption. The effect of crystallinity and water absorption on the dynamic mechanical relaxation behaviour of polycaprolactone. The compressive modulus of the PCL–PHB and PCL–PHBV dual‐leached scaffolds is greatly increased by the blending of … Dr Mike J Jenkins. Three experimental mineral-doped formulations were prepared (PCL-10CaSi, PCL-5CaSi-5DCPD, PCL-10CaSi-10DCPD); pure PCL scaffolds constituted the control group. Metallurgy and Materials, School of Engineering, University of Birmingham, Edgbaston B15 2TT, UK. cal properties, decreasing water absorption or restraining retrogradation of these biodegradable blends. In this study, starch/polycaprolactone (SPCL12) and cross-linked starch/PCL (SPCL10) blends were prepared, charac-terized and used for biological nitrate removal in order to reduce the cost of solid carbon source.
