This study details the design, fabrication, clinical trials' evaluation, and analysis after application of 3D-printed bone reconstruction implants made nHAp@PLDLLA [nanohydroxyapatite@poly(L-lactide-
The surface modification of poly(lactic acid) (PLA) using hydroxyapatite (HAP) particles via Langmuir-Blodgett (LB) and Langmuir-Schaefer (LS) approaches has been reported. HAP monolayer was characterized at the air/water interface deposited on three-dimensional (3D) printed acid). deposition LS approach led to a larger coverage in comparison LB method, which produces less uniform coating because aggregation particles. After transfer PLA surface, wettability values remained within desired...
Bio-based composites made of poly(l-lactic acid) (PLLA) and pine wood were prepared by melt extrusion. The compatibilized impregnation with γ-aminopropyltriethoxysilane (APE). Comparison non-compatibilized formulation revealed that APE is an efficient compatibilizer for PLLA/wood composites. Pine particles dispersed within PLLA act as nucleating agents able to start the growth crystals, resulting in a faster crystallization rate increased crystal fraction. Moreover, have slightly lower...
Bio-based composites made of poly(L-lactic acid) (PLLA) and β-cyclodextrin/d-limonene inclusion complex (CD-Lim) were prepared by melt extrusion. Encapsulation volatile d-limonene molecules within β-cyclodextrin cages was proven to be a successful strategy prevent evaporation during high-temperature processing. However, small amounts limonene released upon processing, resulting in the plasticization polymeric matrix. Morphological analysis revealed good dispersion filler, which acted as...
Composites made of linear low-density polyethylene (LLDPE) and β-cyclodextrin/d-limonene inclusion complex (CD-lim) were prepared by melt extrusion to develop a novel food packaging material. Scanning electron microscopy evidenced fairly good dispersion the filler within polymeric matrix. Infrared spectroscopy coupled with thermogravimetric analysis confirmed presence CD-lim in composites, proving that applied technology including essential oil β-CD cages allows for preventing sizable loss...
Polyolefins such as polypropylene are used in an immensely broad range of commodity products and account for the largest volume synthetic polymers generated worldwide. For this reason, family thermoplastics contributes significantly to solid waste both on land ocean. One viable approach mitigate growing problem simultaneously reduce cost dependence petroleum-based relies blends wherein added biopolymer can promote natural biodegradation. Due their chemical dissimilarity, however, nonpolar...
Abstract Composites made of poly( l ‐lactic acid) (PLLA) and β‐cyclodextrin/D‐limonene inclusion complex (CD‐Lim) are prepared to develop novel food packaging material with antibacterial properties. The composites formulated bio‐based materials that also biodegradable. addition CD‐Lim PLLA results in enhanced permeability water uptake. Optical properties PLLA/CD‐Lim significantly vary compared plain PLLA, partial loss transparency gloss, but sizably increased barrier UV light, which imparts...
This work presents selected properties of polypropylene-based (PP) composites modified with an organic filler, namely walnut shells (NUT).Two series were prepared via a twin-screw extrusion process, followed by injection molding.The first series, named PP/NUT, contained 10, 20 and 40 wt% shell powder, while the second, abbreviated PP/NUT/MAPP, apart from nut filler included polypropylene-graft-maleic anhydride (MAPP), which was intended to promote adhesion between polymer filler.The...
Abstract Linear low‐density polyethylene (PE) containing an inclusion complex composed of β‐cyclodextrin and d ‐limonene (CD‐lim) is proposed as innovative food wrapping material with antimicrobial features. PE/CD‐lim composites are prepared by conventional, high‐volume processing, the optical mechanical properties developed formulations appear suitable for their use packaging materials. Compared to plain PE, films have improved haze UV–vis outcomes, but also decreased gloss values. Addition...
Wood-polymer composites based on high-density polyethylene and two types of pine-wood filler were investigated.It is shown that the addition long wood fibres to common leads a substantial increase in stiffness, i.e. from 504 MPa for PE-HD up 1526 with 60% fibres.Moreover, morphological investigations revealed superficial particles sufficiently embedded base polymer ensuring protection against higher moisture uptake rates.
Herein, a chitosan-based thermosensitive hydrogel (CH) containing hydroxyapatite (HAp), poly(lactic acid) (PLDLLA) or their mixture is proposed as an innovative, biomimetic composition with antimicrobial and bone-forming properties for guided bone regeneration. The modified hydrogels were synthesized characterized to verify suitability the treatment of
