Zjawisku temu towarzyszy wzrost istotnych problemów gospodarczych i ekonomicznych. Problem ten szczególnie dotyczy dużych aglomeracji miejskich. Wzmiankowane fakty spowodowane są trudnościami związanymi z biodegradacją, różnorodnością odpadów pochodzenia polimerowego oraz niewystarczającym stopniem ich recyklingu [1,2]. Innym problemem jest konieczność poprawy właściwości polimerów. W szczególności to dotyczy zwiększenia modułu Younga, pozwalającą na poszerzenie aplikacji tych polimerów.

Ceramics biomaterials are used as components of hip implants, dental implants, middle ear implants and heart valves. Porous or particulate calcium phosphate ceramic materials such as tricalcium phosphate (TCP) have proved successful for resorbable hard tissue replacements when low loads are applied to the material. The aim of the present work was to evaluate the biological characteristics of the biomaterial developed. Interactions of TCP with polyacrylate polymers in aqueous dispersions were characterised using X-ray diffraction, Fourier transform infrared spectroscopy, pH determination and viscosity measurements.

Therefore, more and more waste is recycled. To increase the strength properties of recycled materials, they are reinforced with various types of fillers such as natural. Over the last few years, fillers from tuffs of volcanic origin have been gaining in popularity. It is characterized by a low mass, high hardness, high matrix adhesion, which allow for uniform distribution of particles in the volume of the material. In this paper, composites based on recycled polystyrene waste with tuff microparticles in mass weight of 10% and 20% were produced by injection moulding. The basic mechanical properties at room temperature (+24°C)-24 and +80°C were evaluated. The aim of the study was to demonstrate the possibility of using the mineral filler particles as compatibilizer for recycled polystyrene waste of poor quality.

BIOPOLYAMIDE MATRIX COMPOSITES WITH WALNUT SHELL FLOUR SURFACE-MODIFIED BY SILVER NANOPARTICLES Summary. In the study, biocomposites of polyamide 10,10 with 10%wt. and 30%wt. of walnut shell flour were characterized in respect to structural and extracorporeal medical applications. Preliminary attempts were made to cover the composites with silver nanoparticles. For comparison purposes, specimens of PA 10.10 with 30%wt. glass fibers were also manufactured and tested. Mechanical properties were tested and the composite structure was observed using scanning electron microscope. Surface roughness parameters were measured. Water absorption and its influence on mechanical properties was assessed after 7 days of soaking. The biocomposites showed an increase in modulus of elasticity, higher ductile properties and better surface quality than composites with glass fibers. Surface modification with silver nanoparticles was indicated as an interesting solution, especially for medical equipment, however the techniques of application should be refined

The research was done on blends of high density polyethylene (PE-HD) and two commercial biopolymers intended for packaging applications. The mechanical properties, microstructures, water absorptions and DSC results were analyzed. A significant decrease in the blend properties compared to neat polyethylene and biopolymers is a warning against the poor waste management of biodegradable products.

Therefore, an increasing interest in biodegradable and bio-compostable materials has been observed in the recent years. Bio-based materials are becoming more and more popular, especially in applications where biodegradability provides an advantage for customers and environment. However, biodegradable materials are more expensive compared with durable plastic materials, so to reduce costs and in order to improve their mechanical properties, biocomposites are created by reinforcement with natural fibers: cellulose, hemp, jute, cotton, etc. This paper is focused on the investigation of the selected group of biocomposites based on poly (3-hydroxybutyrate-co-3-hydroxyvalerate) with the addition of 15 wt% of various fillers (nanocellulose, walnut shell flour, eggshell flour, and tuff). Thus far, there is limited information concerning comparison of the different natural fillers introduced into the poly(3-hydroxybutyrate-co-3-hydroxyvalerate) matrix. Here, the following mechanical properties were evaluated: the tensile strength, modulus of elasticity, strain at break, flexural modulus, and flexural stress at 3.5% strain. The tensile test was performed at various temperatures (− 24, + 23, and + 60 °C), followed by samples conditioning in water and compost. Thermal behavior of the biocomposites was studied by means of differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA). The study showed that the value of the elasticity modulus of each composite was higher in comparison with neat poly (3-hydroxybutyrate-co-3-hydroxyvalerate), at each of the above temperatures. The factor responsible for the enhancement of the mechanical properties of composites (enhancement of the stiffness of the material) was the increase in crystalline phase content in composites. Interestingly, at − 24 °C, all of the analyzed composites exhibited over twofold increase in tensile strength which was accompanied by an almost 30% increase in elastic modulus. This phenomenon likely resulted from an increase in tensile strength and an increase in internal stress at interfaces within the components of the composites during tests. It was also observed that both conditioning in water and degradation in the compost heap led to a considerable decrease in mechanical properties of the examined composites. The scanning electron microscopy analysis, carried out to assess the distribution of particles and the adhesion of fillers to the matrix, revealed that the size and the shape of the particles affected the mechanical properties of the composites.
