The trial-and-error method currently used to create formulations with excellent printability demands considerable time and resources, primarily due the increasing number of variables involved. Rheology serves as a relatively rapid highly beneficial for assessing materials evaluating their effectiveness 3D constructs. However, data obtained can be overwhelming, especially users lacking experience in this field. This study examined rheological properties agar, hydroxypropyl methylcellulose,...
Natural fibre reinforced polylactic acid (PLA) foams, as potential green replacements for petroleum-based polymer were investigated.Highly porous (ε > 95%) microcellular PLA foams manufactured by supercritical CO 2 assisted extrusion process.To overcome the inherently low melt strength of PLA, epoxy-functionalized chain extender was applied, while talc added to improve its crystallization kinetics.The combined application and effectively promoted formation uniform cell structures.The effect...
Aerogels and cryogels were obtained from cellulose-based textile waste.
Structured and fully bio‐based polymer assemblies based on chitosan micro‐ nano‐particles poly(lactic acid) (PLA) were developed using a continuous cast‐film extrusion process. The microstructure thermal properties of the resulting biocomposite films are studied. Dispersion size distribution particles within analyzed by optical microscopy laser diffraction. Results show homogeneous dispersion with no agglomeration, due to favorable physico–chemical interactions between PLA weak particle...
Dispersing at the molecular level a drug in polymer matrix is major challenge to be addressed by pharmaceutical industry enhance its bioavailability or control release. Melt extrusion and supercritical CO 2 ‐aided melt of solid formulations were performed dissolution rate carvedilol, taken as model poorly soluble drug. The presence improved processability polyacrylate (Eudragit E) through plasticizing effect. method was found gentle compared with owing shorter residence time lower processing...
ABSTRACT In this study, the outcome of operating conditions extrusion assisted by supercritical CO 2 for manufacture poly(lactic acid) foams was investigated. It found that temperature before and inside die most prominent parameter to tune foam properties. Foam porosity as high 96% could be obtained (for between 109 112 °C), representing a total expansion exceeding 30. range, low crystallinity (≈6%) induced giving with radial i.e., large diameters open porosity. At °C, able greatly expand...
Semi-solid extrusion (SSE), an additive manufacturing technique, is gaining significant attention for the printing of thermosensitive drugs. Hydrogels, one materials used in SSE, have emerged as a focus pharmaceutical applications due to their ability control release therapeutic agents spatially and temporally. Understanding non-Newtonian flow evaluating mechanical properties hydrogel-based during is, however, essential successful 3D printing. Thus, users often find themselves conducting...
