Improved the surface properties of carbon fiber through hyperbranched polyaryletherketone sizing

Abstract

A heat‐resistant soluble hyperbranched polyaryl ether ketone (HPAEK) is synthesized as the main resin of sizing agent and coated on the surface of carbon fiber (CF) with active group. As a result, the monofilament tensile strength of CF is increased by 12.00% and due to the improved fiber surface wettability and interface compatibility between CF and polyether ether ketone (PEEK), a 68.29% increase of interlaminar shear strength is achieved.

Hydroxyapatite/hyperbranched polyitaconic acid/chitosan composite scaffold for bone tissue engineering

“…[6][7][8][9] Amongst those materials, hyperbranched polymers are considered an important class of active materials whose unique properties as high number of active groups and globular structure with several potential applications. [10][11][12] Several hyperbranched polymers with bioactive properties were studied as tissue engineering scaffolds such as polylactic acid (PLA), hyper-brancher polyglycerol (HPG), polycaprolactone (PCL), polurethane (PU) and poly ethylene glycol (PEG), and polylactic glycolic acid (PLGA). [12][13][14][15][16][17][18] On the other hand, chitosan (CS) is an important natural biopolymer as it is biocompatible, biodegradable and can be shaped into different structures including porous structure in addition to its osteoconduction and intrinsic antibacterial nature.…”

Polydopamine and polyethyleneimine comodified carbon fibers/epoxy composites with gradual and alternate rigid‐flexible structures: Design, characterizations, interfacial, and mechanical properties

“…Wu et al [ 21 ] coated sizing on the fiber surface and investigated the effects of the degree of chemical interaction between fibers and surface sizing on the interfacial properties of EP composites. Ma et al [ 22 ] synthesized a hyperbranched soluble sizing agent of polyaryl ether ketone, and improved the ILSS value by 68.29% compared with the unmodified fiber composites. Wen et al [ 23 ] modified the CF surface by a two‐step treatment of electrochemical oxidation followed by grafting silane coupling agent, and the interfacial properties of the formed carbon fiber‐epoxy (CF/EP) composites were improved greatly.…”

Multi‐functional structural supercapacitor based on manganese oxide‐hydroxide nanowires modified carbon fiber fabric electrodes

“…[9][10][11][12] Carbon fiber reinforced plastics (CFRPs) have been widely applied in manufacturing high-performance lightweight structural components for automotive and aerospace industries owing to their high specific strength and stiffness. [13][14][15] Moreover, carbon fibers (CFs) show appreciable electrical conductivity, [16] which enables them to be used as electrodes for supercapacitors, and therefore considerable efforts have been devoted to developing CFRP-based structural supercapacitors. [17,18] However, pristine CFs generally present low specific capacity due to its relatively low specific surface area and surface activity, and thus it is difficult to be directly used as electrode.…”
