Abstract:
Protective coatings and methods for forming them are disclosed wherein the coatings have increased abrasion, impact and scratch resistance as compared to known coatings. The coatings are made from environmentally friendly materials such as polylactic acid which can be derived from corn. The materials can be used to provide a protective coating on their substrate materials including especially wood for flooring and furniture. The coatings can have a hardness as measured on the Shore D Scale that can reach at least 75 to about 85 and enhanced resistance to abrasions, impact or scratches and can be used to coat flooring or furniture surfaces. The coatings can contain from about 1 to about 10 mass percent of triallyl isocyanurate with respect to polylactic acid.

Abstract:
A bone implantable medical device made from a biocompatible material, preferably comprising titanic or zirconia, has at least a portion of its surface modified to facilitate improved integration with bone. The implantable device may incorporate a surface infused with osteoinductive agent and/or may incorporate holes loaded with a therapeutic agent. The infused surface and/or the holes may be patterned to determine the distribution of and amount of osteoinductive agent and/or therapeutic agent incorporated. The rate of release or elution profile of the therapeutic agent may be controlled. Methods for producing such a bone implantable medical device are also disclosed and employ the use of ion beam irradiation, preferably gas cluster ion beam irradiation for improving bone integration.
Abstract:
A method of grafting monomers (M) in a deep layer (1) in an organic material by using an ion beam (X), wherein the ion dose per unit area is selected so as to be in the range of 1012 ions/cm2 to 1018 ions/cm2 so as to create a reservoir of free radicals (1) within a large thickness in the range 0 nm to 3000 nm. Hydrophilic and/or hydrophobic and/or antibacterial monomers (M) are grafted in the reservoir of free radicals (1). Organic materials with hydrophobic, hydrophilic, and/or antibacterial properties that are effective for long-term use are thus advantageously obtained.
