Abstract: Composite porous hydrophobic membranes are prepared by forming a perfluorohydrocarbon layer on the surface of a preformed porous polymeric substrate. The substrate can be formed from poly(aryl ether ketone) and a perfluorohydrocarbon layer can be chemically grafted to the surface of the substrate. The membranes can be utilized for a broad range of fluid separations, such as microfiltration, nanofiltration, ultrafiltration as membrane contactors for membrane distillation and for degassing and dewatering of fluids. The membranes can further contain a dense ultra-thin perfluorohydrocarbon layer superimposed on the porous poly(aryl ether ketone) substrate and can be utilized as membrane contactors or as gas separation. membranes for natural gas treatment and gas dehydration.

Abstract: The present invention discloses a digital signature scheme based on braid group conjugacy problem and a verifying method thereof, wherein a signatory S selects three braids x?LBm(l), x??Bn(l), a?Bn(l), and considers braid pair (x?,x) as a public key of S, braid a as a private key of S; Signatory S uses hash function h for a message M needing signature to get y=h(M)?Bn(l); generating a braid b?RBn?1?m(l) randomly, then signing M with a and b to obtain Sign(M)=a?1byb?1a; a signature verifying party V obtains the public key of S, calculating the message M by employing hash function h, obtaining the y=h(M); judging whether sign(M) and y, sign(M)x? and xy are conjugate or not, if yes, sign(M) is a legal signature of message M; the present invention reduces the number of braids involved and the number for conjugacy decision without reducing security, thereby improving the operation efficiency of signature.

Abstract: Functionalized porous poly(aryl ether ketone) articles are prepared by reacting ketone groups in the backbone of poly(aryl ether ketone) polymer with a primary amine reagent. Preferred functional primary amines are primary aliphatic amines or substituted hydrazines containing one or more target functional groups including polar groups, such as hydroxyl groups, ˜OH, amino groups, ˜NH2, ˜NHR, ˜NRR?, and ethylene oxide groups, ˜OCH2CH2—, negatively or positively charged ionic groups, such as ˜SO3?, ˜COO?, and ˜NH4+ groups, hydrophobic groups such as siloxane or perfluorcarbone groups, and non-polar groups, such as linear or branched hydrocarbon groups. The functionalized porous poly(aryl ether ketone) article can be prepared by reacting primary amine with a pre-formed, shaped porous poly(aryl ether ketone) article or by functionalizing the surface of a non-porous precursor article that is subsequently converted into a porous article.
