Yes, polysaccharides and polymers are closely related. Polysaccharides are a specific type of polymer, which are large molecules made from many smaller, repeating units called monomers. Polymers can be natural or synthetic and encompass a wide range of materials, including plastics, proteins, and nucleic acids. Polysaccharides are polymers whose repeating units are sugar molecules, linked together by glycosidic bonds. Examples of polysaccharides include cellulose, which is found in plant cell walls, and glycogen, used for energy storage in animals. The general concept of polymers covers a broad range of substances, but polysaccharides specifically refer to those made of sugars, showcasing their importance in both biological structures and processes.

Fracture toughness is a critical property that measures a material's resistance to crack propagation. For polymers, this value is significant because it indicates how these materials will behave under stress, particularly at the point of a crack. Typically, polymers exhibit lower fracture toughness values compared to metals and ceramics due to their molecular structure. However, these values can vary widely depending on the type of polymer, its molecular weight, branching, cross-linking, and the presence of plasticizers or reinforcing fibers. For instance, the fracture toughness (KIC) of common engineering thermoplastics such as polyethylene (PE) ranges from 0.1 to 1.0 MPa√m, while for more robust materials like some grades of polycarbonate (PC), it can be around 2.0 MPa√m. To improve the fracture toughness of polymers, techniques like rubber toughening or the use of nanocomposites have been employed successfully. These methods involve incorporating elastomeric particles or nanoscale reinforcements into the polymer matrix, which can arrest crack propagation by various mechanisms.

To filter MBHA resin, first, swell the resin in an appropriate solvent like dichloromethane (DCM) or dimethylformamide (DMF) for at least 30 minutes to ensure it's fully expanded. Next, pour the swollen resin into a filtration setup, typically a glass fritted funnel or a sintered glass crucible, compatible with the solvent used. Apply a gentle vacuum to assist the filtration process, avoiding too strong a vacuum that might dry out the resin or pull resin particles through the filter. After filtration, the resin can be washed directly on the filtration setup with the appropriate solvent to remove any impurities or unreacted materials. The washed resin is then ready for subsequent chemical steps or storage. Ensure all procedures are performed under a fume hood to handle volatile solvents safely.
