【摘要】：設計了一類由聚4-乙烯基吡啶(P4VP)、含彎曲樹枝化分子12CBP以及線性分子PDP組成的三元共混體系,其中12CBP和PDP端基均為酚羥基,可與P4VP側基的吡啶環(huán)上的N原子進行氫鍵復合.傅立葉變換紅外光譜、示差掃描量熱法、偏光顯微鏡、小角X射線散射和原子力顯微鏡等多種研究表明該共混體系為均相體系,三組分自組裝形成以P4VP為主鏈,12CBP和PDP為超分子側鏈的"無規(guī)共聚物"P4VP(12CBP)x(PDP)y(x+y=1).該超分子側鏈共聚物的聚集態(tài)結構與小分子12CBP和PDP相對含量有關.當12CBP含量x≥0.5時,體系組裝形成六方柱狀相結構,柱子的直徑隨著體系中12CBP含量減少而逐漸減小.當12CBP含量0.5時,即使少量12CBP的引入也會引起體系層狀相結構的破壞,體系表現(xiàn)為無定形狀態(tài).
[Abstract]:A kind of ternary blend system consisting of poly (4-vinylpyridine) (P4VP), including bending dendrimer 12CBP and linear molecular PDP was designed. The terminal groups of 12CBP and PDP are phenolic hydroxyl groups, which can be recombined with N atoms on the pyridine ring of P4VP side group. Fourier transform infrared spectroscopy (FTIR), differential scanning calorimetry (DSC), polarizing microscope, small angle X-ray scattering and atomic force microscope (AFM) show that the blend is homogeneous. The "random copolymer" P4VP (12CBP) x (PDP) y (x yt1) was formed by self-assembly of three components with P4VP as main chain and PDP as supramolecular side chain. The aggregation structure of the supramolecular side chain copolymer is related to the relative content of 12CBP and PDP. When the content of 12CBP x 鈮，
