Supervisor

Prof. Dr. Svea Petersen

Project

Modification and characterization of polymers for medical applications

 

Polymers have found widespread applications in biomedicine, in particular as implant bulk or coating material or as carrier in drug delivery systems. In our lab, we focus on the establishment and characterization of surface modification reactions of polymers including the provision with a local drug delivery function and/or biofunctionalization in order to selectively control cell-implant interactions.

Tasks

 

  1. Chemical surface modification and biofunctionalization of polymers for enhanced biocompatibility and their characterization via contact angle measurements, FTIR, electron microscopy, etc.
  2. Establishment of polymer-based local drug delivery systems and performance of in vitro drug release studies via HPLC and fluorescence spectroscopy.

Requirements

Lab skills are desired, as independent chemical work will be required. A basic understanding of polymers and surface chemistry is desired.

Language Skills

Proficient in English or German

Duration

3-6 months

Possible Beginning

Project

MultiHemp - Multipurpose hemp for industrial bioproducts and biomass

In recent years, the increasing need for renewable resources and sustainable materials has fuelled a renewed interest in natural plant fibers. Actual markets of natural fibers are dominated by cotton that, on average, accounts for over 75% of the global natural fiber production. Cotton poses particular concern with regard to sustainability as it has one of the worst environmental footprints of any crop, with particularly high demands for irrigation and agricultural chemicals. In contrast, hemp is a highly productive crop with low demand for water and agrochemical applications. Besides textiles, a wide range of technical applications of natural fibers has already been developed to date, with insulating materials, biobased-composites and geotextiles being the most advanced and promising. Future demand of natural fibers is expected to grow rapidly, thanks to expanding industrial applications that can be addressed by bast fibers.

This research project aims at developing hemp genotypes with enhanced traits suitable for diverse cultivation environments and to provide improved feedstock for a wide array of innovative end products generated within an integrated biorefinery. Our aim is to develop a modular biorefinery in which market forces will dictate the flow of raw material into differing product options. The production of long bast fiber for technical textiles and high-quality composites will be coupled to that of short bast fiber for injection molded bio-composites and insulation products, as well as shives for low carbon construction materials, oil for health and personal care applications, protein for food and feed, and high value chemicals such as phytosterols, waxes, and essential oils.

The research at HSB will focus on fibers, insulation products and composites.

Internship in Bio-inspired natural & cellulose fiber-reinforced composites with ductile behavior

at Bremen City University of Applied Sciences

Supervisor

Prof. Dr.-Ing. Jörg Muessig & Dr.-Ing. Nina Graupner

Project

Bio-inspired natural & cellulose fiber-reinforced composites with ductile behavior

Biological materials show impressive combinations of mechanical properties like strength and toughness and are optimized in the evolutionary process to meet nature’s requirements. For engineering materials, there is more to learn from nature than replicating one structure: learning from the general principles and structural hierarchy of these natural materials can give valuable ideas, for example, for the improvement of mechanical properties of materials.

Natural solutions as concept generators for technical composites, should lead to a further optimization of the mechanical properties of cellulose fiber-reinforced composites. The advantages of different reinforcing fibers are brought together in one composite. Bast fiber-reinforced composites generally display good strength and stiffness with brittle impact behavior at the same time. In contrast to this regenerated cellulose fiber-reinforced composites show a high ductility and good impact properties. A previous work has shown that a mixture of both types of fibers lead to a significant improvement of the impact properties compared to bast fiber-reinforced composites. A further improvement of these properties has been succeeded by using natural solutions. Nature offers several examples, which are optimized to stress as well as impact. For example, symmetric layered structures in the petioles of red rhubarb, or even asymmetrical layers in the pericarp of the coconut. These structures were transferred to technical solutions and have been implemented in compression molded layered composites by using ramie (high stiffness, low elongation), hemp (lower stiffness and higher elongation compared to ramie) and lyocell fibers (lower stiffness and higher elongation compared to hemp) as reinforcement for a plastic matrix. The results have shown that the impact properties could be significantly improved by such a layered structure compared to composites which were produced from a mixture of the different fibers. The tensile characteristics were not affected by the layered structure. The investigations show that the concept of the development of biomimetic fiber composites can result in an optimization of the mechanical characteristics of classical composites. The unusual structures from the engineering point of view of the red rhubarb petioles and the fruit shell of the coconut have led to a further optimization of cellulose fiber-reinforced PLA composites.

 

Apart from these two examples there are many interesting biological structures which may be used to improve the characteristics of cellulose fiber-reinforced composites. If you are interested in such research projects do not hesitate to contact us!
