“…Surface modification technology can be used to make up for this deficiency on the premise of maintaining the original properties of products [ 31 ]. There are mainly surface chemical reaction method, surface grafting method, surface composite method, and other technologies [ 32 ]. Coupling agents are the most commonly used surface modifiers, such as titanate coupling agents, silane coupling agents, and aluminate coupling agents, etc.…”

Ammonium polyphosphate (APP) was successfully modified by a titanate coupling agent which was compounded with benzoxazine (BOZ) and melamine (ME) to become a new type of intumescent flame retardant (Ti-IFR). Ti-IFR and CaCO3 as synergists were utilized to modify polyoxymethylene (POM), and the flame-retardant properties and mechanism of the composites were analyzed by vertical combustion (UL-94), limiting oxygen index (LOI), TG-IR, and cone calorimeter (Cone), etc. The results show that Ti-IFR can enhance the gas phase flame retardant effect, while CaCO3 further strengthens the barrier effect in the condensed phase. When they were used together, they can exert their performance, respectively, at the same time showing excellent synergistic effect. The FR-POM composite with 29% Ti-IFR and 1% CaCO3 can pass the UL-94 V0 level. The LOI reaches 58.2%, the average heat release (Av HRR) is reduced by 81.1% and the total heat release (THR) is decreased by 35.3%.

“…Commonly used surface modifications include surface oxidation, plasma treatment, chemical treatment, surface grafting, etc. [6,7] Among them, direct fluorination and plasma treatment are the two most generally used surface modification methods for polymer materials. General and engineering plastics such as PE, PP, PVDF, and PLA have been modified by such two methods for improving wettability, permeability, antifouling properties, etc.…”

For the first time, an ultrathin type of ultra‐high molecular weight polyethylene (UHMWPE) membrane of only 350 nm thickness is surface modified by direct fluorination and plasma treatments. Then a notable suppression in crystallinity is observed. A total of four kinds of thickness, from 350 nm to 6 µm, are investigated to correlate the modification effect on the thickness. Microscopically, the continuous shish‐kebab structure transforms into scattered lamellae clusters. And the damage to the surface morphologies increases as the thickness decreases, yet the resultant contact angles remain almost constant. Especially for the 350 nm thin UHMWPE, the mildest fluorination treatment slightly changes the contact angle, while the multiscale structure changes significantly from crystalline to mesoscopic level. As thickness decreases from 6 µm to 350 nm, the modified volume ratio of membranes increases, and the volumetric modification is almost realized for the 350 nm membrane.

Bone tissue engineering is constantly in need of new material development with improved biocompatibility or mechanical features closer to those of natural bone. Other important factors are the sustainability, cost, and origin of the natural precursors involved in the technological process. This study focused on two widely used polymers in tissue engineering, namely polylactic acid (PLA) and thermoplastic polyurethane (TPU), as well as bovine-bone-derived hydroxyapatite (HA) for the manufacturing of core-shell structures. In order to embed the ceramic particles on the polymeric filaments surface, the materials were introduced in an electrical oven at various temperatures and exposure times and under various pressing forces. The obtained core-shell structures were characterized in terms of morphology and composition, and a pull-out test was used to demonstrate the particles adhesion on the polymeric filaments structure. Thermal properties (modulated temperature and exposure time) and the pressing force's influence upon HA particles' insertion degree were evaluated. More to the point, the form variation factor and the mass variation led to the optimal technological parameters for the synthesis of core-shell materials for prospect additive manufacturing and regenerative medicine applications.Coatings 2020, 10, 283 2 of 18 importance. Among these, PLA was widely used, mainly due to its biocompatibility with the human organism and the advantageous synthesis alternative from sustainable natural resources (e.g., beet or maize) [14]. Along with PLA, TPU was remarked in the additive manufacturing technology [15]. The TPU applications in the medical field spread from blood vessels, implants, and prosthetics, to scaffolding in tissue engineering, dialysis membranes, or breast implants [16].Furthermore, naturally derived hydroxyapatite (HA) is a bioactive ceramic, with similar chemical and structural properties to the mineral component of the natural bone tissue, and exceptional biocompatibility and osteoconductivity. HA can be synthesized from various renewable resources (e.g. fish, sheep, cattle or bovine bones [17,18] or marine shells [19,20]).Along with the development of new biomaterials, the cost-efficient and highly performant processing techniques for final products manufacturing are also in need of improvement. Additive manufacturing (AM) or 3D printing can be considered 21st century technology due to the possibility to attain patient-customized and adapted products [14]. However, the most widely and accessible used technique in orthopedics is fused deposition modeling (FDM) or fused filler fabrication (FFF) [8,14,21,22], which provide 3D scaffolds with a well-defined design by extruding a digital 3D model from thermoplastic polymeric materials heated to their melting point [22].This study aims to provide a new core-shell material that can be used in the FDM technique, targeted due to its rigorous control of parameters (temperature, bed temperature, feed rate, printing speed, etc.) [23][24][25][26][27].Therefore, thi...
