A non-baked pencil lead including a wax that is solid at normal temperature, a colorant, a filler, a water-soluble resin, and a cellulose fiber, wherein a ratio of a flaky substance in the filler is 20 mass % or less, and the ratio of an aggregate particle in the filler is 80 mass % or more.

A pencil lead may have sufficient strength at the time of writing even when a tip is pointed, less deterioration due to moisture absorption, and erasability, and may be manufactured without applying a temperature exceeding 500 C. Such a pencil lead may contain at least a clay in which the peak of 2 appears at 12.40.5 and/or 24.51.0 as measured by XRD, a coloring material, and an alkali metal element. Manufacturing the pencil lead may include drying a clay at 50 C. to 500 C. such that a peak of 2 appears at 12.40.5 and/or 24.51.0 as measured by XRD, mixing the dried clay, a coloring material, and an alkali metal hydroxide aqueous solution, molding the mixture, and then performing firing at 50 C. to 500 C.

A superhydrophobic anti-fouling crayon comprises a composition of capsaicin, wax, polydimethylsiloxane (PDMS), polytetrafluoroethylene (PTFE), and triglyceride, where the crayon is water insoluble, superhydrophobic, and transparent to electronic sensor and antennae signals. The crayon is rubbed onto the marine surface such that a layer of the composition of the crayon is applied thereto to produce a durable coating that inhibits fouling.

A system, composition, and method are disclosed for producing superhydrophobic and antifouling polymer materials. The invention incorporates antifouling agents such as capsaicin, medetomidine, tralopyril, or zinc pyrithione together with hydrophobic additives such as polydimethylsiloxane, polytetrafluoroethylene, fluoropolymers, or surface-modified nanoparticles into natural or synthetic rubber and thermoplastic matrices. In one approach, pre-formulated antifouling compositions are added as solid components during compounding, and in another, the polymer itself serves as a carrier medium for direct incorporation of the active ingredients. The compounded materials exhibit controlled release of antifouling agents, low surface energy, and superhydrophobic behavior that reduces drag and resists attachment of marine and freshwater organisms. A manufacturing system may include compounding, monitoring, and forming units, with optional plasma or laser treatment to enhance nanoscale roughness. The invention enables durable, environmentally responsible materials for marine, industrial, and consumer applications requiring long-term fouling resistance.
