Definitions
- the invention relates to a nanofiller and its use in organic and / or inorganic matrix materials and the resulting matrix.
- Fillers have been of great importance in the plastics industry for many years. Basically, this means additives in solid form that differ from the plastic matrix in terms of their composition and structure. Most of these are inorganic, less often organic materials. Inactive or extender fillers increase the amount and lower the price, while active fillers specifically improve certain mechanical or physical properties. The effect of active fillers can have various causes, such as the formation of a chemical bond (e.g.
- Nanoscale fillers or nanofillers with primary particles of approx. 50 nm and below are contained in particular in the (organic / inorganic) nanocomposites that have recently appeared on the market. Due to the small particle size of the filler and the extremely high surface areas, special mechanical properties are formed which make the corresponding nanocomposites highly resilient. For example, nature turns in Bone, tendon and tooth material on such nanofillers.
- the polyhedral oligomeric silasesquioxanes that have become known in the literature also have primary particle sizes of 1 to 3 nm (product information Hybrid Plastics 2000, www.hybridplastics.com), but these are not in the solid state, but the much larger agglomerates are generally formed. Even in the dissolved state, aggregates of about 30 to 50 nm in size are said to be present.
- micronizing devices e.g. With a jet mill or jet mill, the agglomerates occurring in the solid state can be ground, but the resulting particle size is still in the ⁇ m range and there are no nanoscale particles. This has particular physical reasons. No grinding device can grind well below 1 ⁇ m, since from a certain degree of fineness the particle's rate of division and recombination are in equilibrium.
- the task was to develop a synthesis for nanofillers with primary particle sizes smaller than 20 nm (nanometers), whereby the peculiarity should be that this primary particle size should be retained in a polymer matrix or the formation of aggregates and agglomerates should be prevented.
- the object was achieved by using polyhedral oligomeric silicon-oxygen clusters as nanofillers, which have a maximum of four, preferably only one, reactive site that can be reacted with a matrix and thus have the polyhedral oligomeric silicon-oxygen clusters in a molecular structure a particle size of less than 20 nm.
- Polyhedral oligomeric silicon-oxygen clusters are preferably understood to mean the two classes of compounds of silasesquioxanes and spherosilicates.
- Silasesquioxanes are oligomeric or polymeric substances, the fully condensed representatives of which have the general formula (SiO 3/2 R) n , where n> 4 and the remainder R. Can be hydrogen atom, but usually represents an organic radical.
- the smallest structure of a silasesquioxane is the tetrahedron. Voronkov and Lavrent'yev (Top. Curr. Chem.
- silasesquioxanes of the formula R 8 Si 8 O can be base-catalyzed to functionalized, incompletely condensed silasesquioxanes, such as R Si O 9 (OH) 3 or R 8 Si 8 O n (OH) 2 and R 8 Si 8 O ⁇ 0 (OH) are implemented (Chem. Commun. (1999), 2309-10; Polym. Mater. Sei. Eng. 82 (2000), 301-2; WO 01/10871) and thus as Serve parent compound for a variety of different incompletely condensed and functionalized silasesquioxanes.
- silasesquioxanes (trisilanols) of the formula R Si O 9 (OH) 3 can be converted into appropriately modified oligomeric silasesquioxanes by reaction with functionalized, monomeric silanes (corner capping).
- Oligomeric spherosilicates have a similar structure to the oligomeric silasesquioxanes. They too have a “cage-like” structure. In contrast to the silasesquioxanes, due to their production method, the silicon atoms at the corners of a spherosilicate are connected to another oxygen atom, which in turn is further substituted. Oligomeric spherosilicates can be silylated by suitable silicate precursors (D. Hoebbel, W. Wieker, Z. Anorg. Allg. Chem. 384 (1971), 43-52; PA Agaskar, Colloids Surf. 63 (1992), 131-8; PG Harrison, R. Kannengiesser, CJ Hall, J.
- the spherosilicate with structure 3 can be synthesized from the silicate precursor of structure 2, which in turn is accessible via the reaction of Si (OEt) 4 with choline silicate or through the reaction of waste products from the rice harvest with tetramemyla monium hydroxide (RM Laine, I. Hasegawa, C. Brick, J. Meeting, Abstracts of Papers, 222nd ACS National Meeting, Chicago, IL, United States, August 26-30, 2001, MTLS-018).
