CMC/PVA/CO Composite Film Characterization

Check if the same lab product or an alternative is used in the 5 most similar protocols
The thickness of the CMC/PVA/CO composite films was measured using a hand-held electronic digital micrometer (Mitutoyo, Japan) with an accuracy of 0.01 mm. Composite films with smooth and uniform thickness were selected for measurement. The mean values were calculated from five random positions on each film.
The mechanical properties of the CMC/PVA/CO composite films, including the ultimate tensile strength (TS) and elongation rate at break (EB), were determined using a universal testing machine (AGX-V, SHIMADZU, Kyoto, Japan). Prior to testing, the composite films were cut into rectangular strips (5 × 50 mm2) and mounted in the machine. The initial grip separation and cross-head speed were set at 25 mm and 1 mm/min, respectively. Finally, the TS (MPa) and EB (%) were measured for each composite film according to previous studies [17 (link),30 (link)].

Compressive testing was conducted according to the ISO 5833:2002 [29 ], where cylindrical shaped samples were used (diameter and height are 6 mm and 12 mm, respectively). The machine used was a Shimadzu AGX-V (SHIMADZU corporation, Kyoto, Japan) with a software package (TRAPEZIUM™ X-V) at 20 mm/min crosshead speed. Compressive strength was performed after 3 months of sample aging in PBS at 37 °C.

Check if the same lab product or an alternative is used in the 5 most similar protocols
A 15 W 455 nm compact semiconductor laser module was employed and mounted on a 6‐DOF robotic manipulator (COMAU Racer3). The vertex coordinates and normals were extracted from the prosthesis model for the focal length control. As for the robotic manipulator system, the host PC built the control model designed for path tracking and communicated with dSPACE ds1202 MicroLabBox (5 kHz) with TCP/IP. Then, the MicroLabBox translated the built model into real‐time torque control signal received by Kollmorgen AKD‐P servo drives. Finally, the servo drives controlled the motors of the robotic manipulator. Meanwhile, the manipulator could also feedback information such as current position to the MicroLabBox via servo drives. The finite element analysis (FEA) of the half thighbone model was conducted on COMSOL Multiphysics. The FEA simulation was designed based on the real compressive experiment on the universal material tester. The model is shown in Figure S7 (Supporting Information). In the model, the bottom plate was fixed, and the top plate was loaded with 200 N along the negative direction of the z‐axis. The CFR‐PEEK‐based half thighbone prosthesis model was made by 3D printing (apparatus: WH3D HT220, base material: CFR‐PEEK). After sensor fabrication, the compressive experiment was performed on Shimadzu AGX‐V universal material tester.

A 4th order Hilbert's curve pattern[30] (26 × 26 mm) was printed on an anodized aluminum substrate (40 × 60 mm) with a thickness of 0.8 mm. The pattern was lased at a power of 5 W and scanning rate of 70 mm min−1, and then electrically connected to the copper wires using silver conductive paste. The three‐point bending test was performed on a universal material testing machine (Shimadzu AGX‐V). The electrical signals were measured by a precision SMU (Keysight B2912A).

Thermal-Responsive Shape Memory of PLA/PU Blends

Check if the same lab product or an alternative is used in the 5 most similar protocols
The shape-memory property of PLA/PU blend samples was examined by selecting PUP-30 and PUP-50. The samples were prepared in a dog-bone shape with a standard dimension of 63 mm × 3.5 mm × 3.63 mm, for a fixed gauge length of 7.5 mm. The specimen was analyzed on a Shimadzu AGX-V, with a temperature controller program at a 20 °C min−1 heating rate. The specimen was heated to 60 °C and stressed at a 50 mm min−1 speed to 20% strain with a 5 min holding time. The sample was cooled at 20 °C for 5 min to observe the fixing shape property. Finally, the sample was heated to 60 °C, followed by a release of the applied load at a 0.5 mm min−1 speed for a shape recovery mechanism. The shape memory test was repeated for at least 3 cycles.
The shape-memory property of PUP-50 film sample was also examined on a tensile machine (Tinius Olsen H5KT) at fixed elongations of 10 and 20%. The film was cut to 80 mm × 10 mm × 0.20 mm for a gauge length of 30 mm. The sample was stressed at 20 mm min−1 speed at 25 °C. The fixing shape at 25 °C was calculated using eqn (1). The shape recovery was observed after heating the sample at 50 °C for 5 min. The recovery efficiency was calculated by eqn (2). where L is the maximum length at the maximum strain, FL is the fixing length (residue length at maximum strain) after tensile at 25 °C, and RL is the shape-recovery length after the thermal treatments at 50 °C.

ATR-FTIR (Thermo Fisher Nicolet iS10, USA) was used to verify the modification of the membranes in the range of 4000–400 cm−1. X-ray photoelectron spectroscopy (XPS, Bruker D8 advance, Germany) analysis was carried out to analyze the elemental composition of the membranes. The morphologies and microstructures (SEM, Thermo Scientific Apreo 2C, USA) of membranes are characterized by emission scanning electron microscopy. Energy dispersive spectrometer (EDS, OXFORD ULTIM Max65, Britain) was used to analyze the distribution of various elements on the film. Atomic force microscope (AFM, Dimension ICON, USA) was used to measure the film surface roughness. Automatic specific surface area and pore size analyzer (American micrometrics ASAP 2460) was used to measure the specific surface area of titanium dioxide. High performance automatic mercury porosimeter (micrometrics 9600, USA) was used to measure membrane pore size. Precision electronic universal material testing machine (Shimadzu AGX-V, JP) was used to analyze the mechanical properties of the film. Synchronous thermal analyzer (Mettler Toledo TGA/DSC 3+, CH) was used to analyze the thermal properties of the films.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
