Advantages And Disadvantages

The article presents options for recycling polymers. The use of biodegradable materials is promising. This is a special class of polymers that can decompose under aerobic or anaerobic conditions under the action of microorganisms or enzymes forming natural products such as carbon dioxide, nitrogen, water, biomass, and inorganic salts. (Research purpose) The research purpose is in reviewing biodegradable materials that can be used for the manufacture of products used in agriculture. (Materials and methods) The study are based on open information sources containing information about biodegradable materials. Research methods are collecting, studying and comparative analysis of information. (Results and discussion) The article presents the advantages and disadvantages of biodegradable materials, mechanical properties of the main groups of biodegradable polymers. The article provides a summary list of agricultural products that can be made from biodegradable polymer materials. It was found that products from the general group are widely used in agriculture. Authors have found that products from a special group can only be made from biodegradable polymers with a controlled decomposition period in the soil, their use contributes to increasing the productivity of crops. (Conclusions) It was found that biodegradable polymer materials, along with environmental safety, have mechanical properties that allow them producing products that do not carry significant loads during operation. We have shown that the creation of responsible products (machine parts) from biodegradable polymers requires an increase in their strength properties, which is achievable by creating composites based on them. It was found that the technological complexity of their manufacture and high cost are the limiting factors for the widespread use of biodegradable polymers at this stage.

Using supercritical carbon dioxide (scCO2) as an alternative to conventional methods in the preparation of porous biodegradable polymer and polymer/nanocomposites for tissue engineering has attracted increasing interest in recent years due to the absence of using organic solvents and the ability to incorporate thermosensitive biologicals without loss of bioactivity. Additionally, scCO2can exert a high level of control over porosity and morphology of scaffolds by tuning the processing parameters. This paper describes the newly achievements on the preparation of porous polymer materials using scCO2foaming technology with focus on the porous biodegradable materials and its nanocomposites relevant to tissue engineering.

To improve the simulation accuracy of biodegradable polymer materials degradation model, a parameter optimization model was proposed, and the ant colony optimization algorithm (ACO) was used to solve the model and optimize undetermined parameters of the model. A comparative analysis of the calculation results was progressed which proved that the simulation accuracy of biodegradable polymer materials degradation of model can be significantly improved by using the optimized parameters. This parameter optimization is propitious to demonstrate the science meaning of degradation mechanization and guide the design and product of medical devices.

Film Form

In this paper, the standard procedures for measuring moisture sorption properties of thin film form of polymer materials such as polyethylene terephthalate (PET) using thermo-gravimetry method and permeation method to characterize the moisture diffusion in polymer is presented. Analytical solution of moisture diffusion and FEA implementation using thermal-moisture analogy for comparison with measurements are presented, in which temperature dependent material properties are characterized. The measurement of permeability is used for validation of moisture diffusion characteristics. Nonlinear behavior of moisture diffusion dependent on concentration is investigated using a specimen having diffusion on half side and diffusivity constants are obtained by solving non-Fickian model and minimizing errors of least square with measurement. Application of characterizing moisture sorption properties to moisture effect on the interfacial layer in multi-layered printed circuit board (PCB) and estimation of relative humidity (RH) through permeation of moisture in hermetic sealing of crystal resonator are presented in this paper: i) The discrepancy of moisture concentration at the interlayer in multi-layered PCB was estimated as loading condition varies. ii) Moisture content through sealant based on temperature dependent permeability was estimated using mixture of ideal gases and vapor pressure.

The Impact

Purpose Additive manufacturing requires a systemic approach to help industry on technology applicability research. Towards this end, the purpose of this research is to help manufacturing business leaders decide whether digitalised manufacturing based on additive manufacturing are suitable for engineering applications and help them plan technology transfer decisions. Design/methodology/approach The methodology is based on case study research and action research, involving a mix of quantitative and qualitative research methods. The empirical part involved the study of the fatigue life of industrial component manufactured by laser sintering as well as a combination of quantitative and qualitative methods to define a strategic decision-making. Findings Laser-sintered plastic materials are suitable in end use automotive applications, especially when there are multiple product variations. Fatigue life of the tested coupling meets the design requirements. Additionally, production of mechanical parts can be substituted by additive methods while digitalising the manufacturing process to gain productivity, especially when there is a need for mass-customisation. Research limitations/implications This research relies on a single case study research. The application used is unique and its technical empirical data cannot be transferred directly to other applications. Practical implications Industry practitioners can use this research to shed light on technology transferability challenges considering technical feasibility of additive polymer materials, economic aspects as well as strategic implications for implementing digitalised manufacturing methods based on additive manufacturing. Originality/value This research presents a combined study of technical and strategic factors for additive manufacturing transferability using an industrial mass-customisation case as an example. In addition, a new cost comparison model is presented including the impact of geometry variations.
