The present invention provides an antifouling coating composition, which can form an antifouling coating film capable of giving excellent slime resistance and has a property such that the recrystallization of an antifouling agent in a paint is depressed. The antifouling coating composition of the present invention is obtainable by blending a coating film forming resin (A) with as an antifouling agent, an inorganic copper antifouling agent (B) such as copper suboxide, etc and N,N′-dimethyl-N′-tolyl(N-fluorodichloromethylthio)sulfamide (C). The antifouling agent (B) is contained in an amount of preferably 60 to 1000 parts by weight based on 100 parts by weight of the coating film forming resin (A), and the antifouling agent (C) is contained in an amount of preferably 1.4 to 80 parts by weight based on 100 parts by weight of the coating film forming resin (A) and also the antifouling agent (C) is contained in an amount of preferably 0.1 to 100 parts by weight based on 100 parts by weight of the antifouling agent (B).

摘要:
Composites which include a polymer matrix having natural free volume therein and an inorganic or organic material disposed in the natural free volume of the polymer matrix are disclosed. In addition, methods for making a composite are described. A polymer matrix having free volume therein is provided. The free volume is evacuated, and inorganic or organic molecules are infused into the evacuated free volume of the polymer matrix. The inorganic or organic molecules can then be polymerized under conditions effective to cause the polymerized inorganic or organic molecules to assemble into macromolecular networks. Alternatively, where the polymer matrix contains a functionality, the inorganic or organic molecules can be treated under conditions effective to cause the inorganic or organic molecules to interact with the polymer matrix's functionality. Use of the disclosed composites as photoradiation shields and filters, electromagnetic radiation shields and filters, antistatic layers, heterogeneous catalysts, conducting electrodes, materials having flame and heat retardant properties, components in the construction of electrolytic cells, fuel cells, and optoelectronic devices, and antifouling coatings is also described.
摘要:
This invention relates to an article comprising a bio-supportive media which bio-degrades at a preferred rate, comprising at least one bio-limiting agent and at least one nutritional source on a substrate. The media may be characterized as a polymer, composite, or amalgam of commonly used materials. The invention relates to altering the physical/chemical composition of the media such that biodegradation can occur at a specific, usually accelerated, preferred rate. Further, the biodegradation rate may be managed and balanced concurrently with the ability to provide for the exposure of integral component(s) which are bio-active. This relationship essentially provides for a managed release or managed availability of agent(s) which creates a new set of ecological conditions. These sustained conditions can maintain a micro-habitat; a limited consort of species, often slime which, due to this ecological trophic niche position, can utilize innate allelopathic means to further protect their position and deter predation. The relationships of the nutrients, bio-limiters, and biomass comprise a unique micro-habitat as an interface which provides protection from corrosion and deterioration of the substrate upon which it is fixed, and limits the biomass accumulation on the surface thereby providing control of fouling by reducing higher order organism(s) attachments, which otherwise are very economically costly. Specifically the invention relates to modifying the media formation whether as a polymer or composite or amalgam such that the physical and chemical properties of the media are altered to become more degradable in the host habitat. This is accomplished by altering the polymerization or formation of the composite or amalgam to provide for increased inter-granular or molecular locations which permit enhanced bio-degradative activity. Then by occluding or interspersing physically or chemically an agent which has bio-active properties, the organisms of various species which may attach or be attracted to the surface can be limited by their nutrition and tolerance of bio-active preference without the need for toxification or mechanical removal of undesirable or unwanted organisms as settlers. Once the community of selected organisms establishes a natural equilibrium with the host habitat any capacity for allelopathic protection of the biofilm can be utilized or enhanced by this new and unique biological community to its benefit through management of the media components.
