摘要： Provided is a method for making a porous graphene layer of a thickness of less than 100 nm, including the following steps: providing a catalytically active substrate, said catalytically active substrate on its surface being provided with a plurality of catalytically inactive domains having a size essentially corresponding to the size of the pores in the resultant porous graphene layer; and chemical vapour deposition and formation of the porous graphene layer on the surface of the catalytically active substrate;. The catalytically active substrate is a copper-nickel alloy substrate with a copper content in the range of 98 to less than 99.96% by weight and a nickel content in the range of more than 0.04-2% by weight, the copper and nickel contents complementing to 100% by weight of the catalytically active substrate.

摘要： Method for making a porous graphene layer of a thickness of less than 100 nm with pores having an average size in the range of 5-900 nm, includes the following steps: providing a catalytically active substrate catalyzing graphene formation under chemical vapor deposition conditions, the catalytically active substrate in or on its surface being provided with a plurality of catalytically inactive domains having a size essentially corresponding to the size of the pores in the resultant porous graphene layer; chemical vapor deposition using a carbon source in the gas phase and formation of the porous graphene layer on the surface of the catalytically active substrate. The pores in the graphene layer are in situ formed due to the presence of the catalytically inactive domains.

摘要： Provided herein is a formulation containing a PPG/PEG block-copolymer (I) on average having PEG-blocks in the range of 37-45 terminated on both sides with on average in the range of 6-11 PPG blocks. The PPG/PEG block-copolymer can be end capped with hydrocarbon systems like for example n-butyl. The PPG/PEG block-copolymer (I) is chosen to have a DSC-melting point according to DIN ISO 11357 in the range of 15-37° C. to provide for a cool touch effect and can be applied without encapsulation. Furthermore uses of such a formulation and textiles treated with such a formulation are proposed.
